fix: Allow SHA-256 in PR commit URLs (#10309)

Closes #9129. I decided to try myself in contributing to Forgejo after having found this bug mentioned on Fedi.

I have also added a basic test for this behaviour, but this means that this PR adds a SHA-256 repo to the fixture set, so it can be reused in other tests.
