ci: update tests to run debian trixie, remove manual installation from testing (#11801)

Forgejo CI is currently failing due to changes in debian testing packaging that are not compatible with installing `git` from testing onto a bookworm system (https://codeberg.org/forgejo/forgejo/actions/runs/147815/jobs/2/attempt/1#jobstep-3-144).

Where `git` was being installed from testing it is replaced with just using trixie's `git 2.47.3`.  Where `git-lfs` was being installed, it's been inlined with a simple `update` and `install`.

### Documentation

- [ ] I created a pull request [to the documentation](https://codeberg.org/forgejo/docs) to explain to Forgejo users how to use this change.
- [x] I did not document these changes and I do not expect someone else to do it.

### Release notes

- [ ] This change will be noticed by a Forgejo user or admin (feature, bug fix, performance, etc.). I suggest to include a release note for this change.
- [x] This change is not visible to a Forgejo user or admin (refactor, dependency upgrade, etc.). I think there is no need to add a release note for this change.
