GitHub Actions: switch utility workflows to ubuntu-slim image (#2053)

* Switch pull request labeler to ubuntu-slim image

* Switch mirror workflow to ubuntu-slim image
This also switches the workflow to another mirroring action (https://github.com/marketplace/actions/mirror-to) because previous doesn't work with ubuntu-slim currently.
