fix(ci): use PAT_TOKEN for tag push in release workflow (#193)

The 'Create and push tag' step used the default GITHUB_TOKEN from
actions/checkout, which lacks push permission. This caused a 403 error
when the workflow_dispatch trigger attempted to create and push a tag.

Use the PAT_TOKEN secret (already used for the changelog commit) to
authenticate the tag push.
