            Update packit workflow and remove F42

Until this point, packit didn't handle the Provides section of the
specfile.

Now it will run update-bundled-provides.sh as part of the update
process. I was only able to test this with a very small set of changes
so it might not be ready. Also my knowledge of AWK is very limited.

+# It's designed to work both in Packit automation and as a manual tool for
+# maintainers of this package. It's clearly not package agnostic. Please use
