### Problem
Big instances can have huge authorized_keys files when using OpenSSH instead of the internal ssh server. Forgejo always re-generates the contents of that file when a user is deleted, even if he does not even have a public key uploaded. In case of codeberg.org, a 15MB file gets rewritten. If we batch delete 100 Spam users without ssh keys, we rewrite 1.5GB, this takes time and wears the SSD. In addition, there is a high chance of hitting a race contidion bug, when deleting users in parallel.
### Solution / Mitigation
This patch prevents rewriting authorized_keys files, when not necessary. It greatly speeds up deleting malicious users, saves IO bandwidth and SSD wear. It also greatly reduces the chance of hitting a race condition bug. Fixing the race condition is not the scope of this patch though.

In the combination of events where the user is viewing an action that is completed (and therefore no interval-based loading of logs is occurring), and `loadJob` is called while `loadJob` is already running (commonly from expanding two log sections back-to-back), the second request for loading would be discarded and never occur.
To fix this, the invocation of `loadJob` keeps track of the log cursors it is attempting to load, and an aborted invocation stores its attempted load. If `loadJob` succeeds in loading and finds that an attempt was aborted while it was busy, it will reload the data.
Steps to reproduce:
- Open an Action UI that is already "Done".
- Click on two steps in rapid succession to expand their logs.
- (Race condition) As long as the second click is registered while the first log chunk is being loaded, its data won't load.

As of Forgejo 8.0.1 the release notes were only available in the
description of the corresponding milestone which is problematic for:
- searching
- safekeeping
The release-notes-published directory is created to remedy those problems:
- a copy of all those release notes from the milestones descriptions
is added.
- a reference is added to the RELEASE-NOTES.md file which will no
longer be used.
- a symbolic link to the RELEASE-NOTES.md is added for completeness.
- the release process will be updated to populate release-notes-published.
The RELEASE-NOTES.md file is kept where it is because it is referenced
by a number of URLs.
The release-notes directory would have been a better name but it is
already used for in flight release notes waiting for the next
release. Renaming this directory or changing it is rather involved.
- A softbreak was being preserved during the github legacy callout (this
is likely due to a change in Goldmark) while it should not. This caused
an `<br>` to be present between the attention title and attention content.
- Added unit test.
- For the notifications page the unread and pinned notifications are
gathered for doer those that and are ordered by the updated unix.
MariaDB makes a bad decision (sometimes, for most users it does not make
this decision) with this query, it uses the index for the `updated_unix`
column to speed up this query, however this is not the correct index to
be taking, if the doer does not have more than 20 (the
page size) unread and pinned notifications combined MariaDB will
traverse the whole notifications table before it realizes that there are
no more notifications to be gathered. It instead should use the index
for the `user_id` column (this is what MariaDB already does for most
users), so the list that has to be traversed is limited to the doer's
notifications which is significantly less than the whole notifications
table.
- This is a different approach than what Gitea has taken to solve this
problem, which is to add a index to the (status, userid, updated_unix)
tuple (Ref: https://github.com/go-gitea/gitea/pull/32395). Adding more
and more indexes is not a good way if we can use existing indexes to get
a query to a acceptable performance.
- The code cannot use `db.Find` as it's hard to add a index hint option
specifically for this query and not for the other instances that uses
`activities_model.FindNotificationOptions`.
- Only add a index hint for MySQL as I have not been able to test if
SQLite or PostgreSQL are smart enough to use the better index (as you
need a large enough dataset to test this meaningfully).
- Integration test added to ensure the SQL is run by all databases.

Performance numbers (from Codeberg's database - MariaDB
10.11.6-MariaDB-0+deb12u1):
Currently:
```sql
SELECT * FROM `notification` WHERE notification.user_id=26734 AND (notification.status=3 OR notification.status=1) ORDER BY notification.updated_unix DESC LIMIT 20;
(5.731 sec)
+------+-------------+--------------+-------+--------------------------------------------------+-------------------------------+---------+-------+---------+------------+----------+------------+-------------+

```
Using the better index:
```sql
SELECT * FROM `notification` USE INDEX (IDX_notification_user_id) WHERE notification.user_id=26734 AND (notification.status=3 OR notification.status=1) ORDER BY notification.updated_unix DESC LIMIT 20;

- If a organisation is set to be limited visible, then it will still be
visible for signed-in users. However `UnitPermission` didn't take this
into account, it does now.
- Add unit test.
- Resolves#6141
This Pull Request addresses a race condition in the updateIframeHeight
function where it is sometimes called when the iframe is not fully
loaded or accessible resulting in an alarming error message for the
user.
To address this we:
1. Add defensive programming within the updateIframeHeight function
2. Delay instantiating the intersection observer until the iframe has
loaded
