[GITEA] Wrap branch information in PR list

- On mobile there's not a lot of horizontal space, so sometimes
information such as icons has to be removed or information gets wrapped
in order to not result in overflowing or weird UI behavior.
- On mobile visiting the pull requests list of an repository, it shows
which head branch is merging into which base branch. This wasn't
properly made responsive and with sufficient long branch names (such as
those used in the Forgejo repository) it resulted in weird UI behavior.
- This patch fixes that by allowing it to wrap, such as the behavior in
1.21
- This already has been fixed in 1.21 with
b9baed2c74.
