Allow new file and edit file preview if it has editable extension (#23624)

Close #23579 
Inspired by
[idea](https://github.com/go-gitea/gitea/issues/23579#issuecomment-1475429247)
from @brechtvl
In this PR, the behavior is when extension switches from writatble to
not, preview will hide, and vice versa.

demo:
