Add "Compare" link/button

Feature Description

Good day!

I feel lack of the Compare link/button.

Don't really understand, how do I compare (as a user) two commit's or release's sources? What should I click?

Propose to add the Compare link/buttons:

• on the repository page,
• on the commit page,
• on the release page,
• on the tag page,
• on the commits page (for each commit item),
• on the tags page (for each tag item),
• on the releases page (for each release item).

Thanks!

I don't see any associated Gitea documentation (which maybe should be there), but you can compare two commits/tags/branches by following the steps mentioned in the GitHub docs.

It was introduced in #6991, and after manually testing it by following these docs it works fine.

This does not mean we should blindly follow GitHub; I would welcome some way to access this compare web UI in a more convenient way.

i think it will be super good to have possibility to compare in history what changed per file between commits because sometimes commits could be very big and contain a lot of files.

I'm starting #32786 to make these features easier to implement.
