Remove support for end-of-life Ruby and Rails versions

These removed versions of Ruby and Rails are no longer supported, not
even for security vulnerabilities. Users should be encourage to migrate
away from these EOL environments. End users can continue to use older
versions of the audited gem if they absolutely must use EOL Ruby and
Rails versions, so they will not be locked out.

These Ruby version add a lot of combinations to the growing test matrix.
This wastes resources on GitHub actions and contributors' local
environments. This makes the time to verify CI take longer.

Dropping EOL versions will also allow the project to evolve to use newer
syntax and library capabilities with fewer compatibility concerns. Those
kind of changes were not included here to keep the scope minimal.
