Fixes #28308 - ignore prerelease tags in dependencies

Templates with requirements specifying plugins that contains .rc in their
versions are skipped. E.g. a template needs katello 3.14.0 but 3.14.0.rc1
s installed. The comparison does not work and template is ignored.

We should ignore the .rc tag as 3.14.0.rc1 has all functionality already
and should be only receiving bug fixes. That makes tester life easier,
they don't have to hack templates in order to seed them.
