Khue Doan 172c7c7c2b chore(gitea)!: ugrade Helm chart to v10
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.
