[Oversight]: RPM Fusion option should install tainted repositories if other repositories are already installed

[Clantis]

Problem Description

If you do not have tainted repositories installed, and try to use Linutil to install them after non-tainted repositories are already installed, it will exit with "RPM Fusion already installed", without giving any option to install tainted repositories.

Proposed solution

If non-tainted RPM Fusion repositories are installed but tainted RPM Fusion repositories are installed, ask to attempt installation of tainted RPM Fusion repositories.

Alternatives

Include secondary option to specifically install tainted RPM Fusion repositories that is usable with RPM Fusion repositories installed.

Additional Context

No response
