Fix: docs-latest push workflow not triggered by release

[jprochazk]

What

release.yml contains a bit of code that force-pushes the release branch into docs-latest, which should then trigger a redeploy of rerun.io together with updated env vars, e.g. RELEASE_VERSION set to the newly released version. That did not happen because the default GITHUB_TOKEN generated by GHA cannot be used to trigger other workflows: https://docs.github.com/en/actions/using-workflows/triggering-a-workflow#triggering-a-workflow-from-a-workflow
