dev-util/gitea-runner: bump to 2.1.0 (#8)

Automated bump of `dev-util/gitea-runner` from 2.0.1 to 2.1.0.

- Upstream release: https://gitea.com/gitea/runner/releases/tag/v2.1.0
- Vendor tarball: https://git.azy.dev/azy5030/azy5030-overlay/releases/tag/gitea-runner-2.1.0-vendor

Review checklist:
- [ ] LICENSE still covers all vendored module licenses (`go-licenses report ./...`)
- [ ] BDEPEND Go version matches upstream go.mod (set to >=1.26.0)
- [ ] version ldflags path `internal/pkg/ver.version` unchanged upstream

CI build + `gitea-runner --version` passed in this workflow.
