fix: use nektos/act (→ gitea/act) instead of gitea/runner for workflow parsing

The gitea.com/gitea/runner module path doesn't match its actual module
declaration (gitea.com/gitea/act_runner) and has version compatibility
issues. Switch imports to github.com/nektos/act which is already
replaced by gitea.com/gitea/act v0.261.10 in go.mod — same packages,
proven compatible.
