Add repo removal logic

[l00d3r]

Fixes #182

[Copilot]

Pull request overview

This PR addresses issue #182 by improving repository management during repo/version changes, primarily by removing leftover version-suffixed repo files and standardizing repo file naming so upgrades don’t accumulate stale definitions.

Changes:

• Add cleanup steps on Debian and RedHat families to find and delete repo/key files matching a configurable regex before (re)creating repositories.
• Switch APT/YUM repository file naming to use a consistent, non-version-suffixed repo name (via a fact) and update Molecule tests accordingly.
• Introduce new defaults to control repo base name selection, cleanup regexes, and whether version-suffixed repo files should be removed.
