ci: Remove "ci" GitHub Actions workflow

We would like to switch to exclusively using Packit for building and
testing pull requests, so we are retiring this GitHub Action workflow.

In order to fully disable the action, this commit must be applied on
each branch in the upstream DNF5 repository. Otherwise, the action might
be triggered by a pull request to some stale branch.
