This is a breaking change, see https://gitea.com/gitea/helm-chart#upgrading
before upgrading to avoid losing data. Personally I have my repos saved
in many Git hosting providers so I just nuke it and reinstall.
Fixes changed files detection in pull_request event in Woodpecker.
- Nix is more reproducible (pinned to a specific hash)
- Faster rebuild after changing the package list (due to /nix caching in volume)
- Users can still use make tools (wrapped in Docker) without installing Nix
- Using nix-shell will work if you have nix installed.
