escape filename when assemble URL (#22850) (#22871)

Browse source 
Backport #22850

Fixes: #22843 

### Cause:

affdd40296/services/repository/files/content.go (L161)

Previously, we did not escape the **"%"** that might be in "treePath"
when call "url.parse()".

This function will check whether "%" is the beginning of an escape
character. Obviously, the "%" in the example (hello%mother.txt) is not
that. So, the function will return a error.

### Solution:
We can escape "treePath" by call "url.PathEscape()" function firstly.

### Screenshot:
