Gitea is working on a github actions-like feature: https://blog.gitea.io/2022/12/feature-preview-gitea-actions/

Right now, Studio seems to be hacking together their own log of releases (mapping to the specific commit on master that was 'tagged' to release), but they're not propagating this back to git(ea) in a way where these tags are stored in the repo. We could leverage the releases functionality in gitea to tag commits, run release workflows to deploy, etc. The functionality should be somewhat compatible with github, and if it's a release workflow that pushes an app to an environment (instead of Studio doing this directly) we could help separate such actions and make them independent of Studio.

This could also make it possible for app developers to write their own tests, and run these on PR, release, etc. And it could make it possible for us to extend the template at some point, with a suggested action to run automatically generated tests (#122).
