Use sbt-typelevel-mergify to generate .mergify.yml

This replaces sbt-github-actions with sbt-typelevel-github-actions and
adds sbt-typelevel-mergify to generate the `.mergify.yml` from our
build. The advantage of that approach is that Scala and JDK versions in
the Mergify config are always in sync with the build which is verified
by the CI via the `githubWorkflowCheck` task.
