fix: remove invalid administration permission from release workflow (#158)

`administration` is not a valid scope for the GitHub Actions
`permissions` key, causing a workflow parse failure before any jobs run.

## Change

- Removed `administration: write` from the top-level `permissions` block
in `.github/workflows/release.yml`

The branch-protection lock action already passes `github.token` directly
to `gh api`, so no additional workflow-level permission entry is needed
or valid here.
