Subject: [PATCH 22/30] Add el8toel9 actor to handle directory -> symlink with
 ruby IRB.

The `/usr/share/ruby/irb/` directory is a symlink in RHEL 9.

Simply remove the directory to then let the RPM mechanism create the
correct symlink on update.

Users should not expect to ever retain anything in this directory.
