Subject: [PATCH] [GITEA] Fix generated source URL on rendered files

- The permalink and 'Reference in New issue' URL of an renderable
file (those where you can see the source and a rendered version of it,
such as markdown) doesn't contain `?display=source`. This leads the
issue that the URL doesn't have any effect, as by default the rendered
version is shown and thus not the source.
- Add `?display=source` to the permalink URL and to 'Reference in New Issue' if it's renderable file.
- Add integration testing.

(cherry picked from commit 458f20f862aa33aac080c221d852f176d92eb110)
(cherry picked from commit 5e630d7b10f1655d4bf480aa1ca5c3f9d411c03f)
