[FEATURE REQUEST] rvm deb package support

Is your feature request related to a problem? Please describe.
The rvm Salt module cannot find the rvm binary if it was installed as an apt package.
Salt is hard coded to use /usr/local/rvm/bin/rvm but the apt package installs rvm into /usr/share/rvm/bin/rvm

This causes issues if, for example, RVM was installed from the official rvm PPA https://github.com/rvm/ubuntu_rvm.

You can replicate this by running the following states.
The second state will try to install RVM fresh despite it already being present on the system (https://github.com/saltstack/salt/blob/master/salt/modules/rvm.py#L68)

rvm:
  pkgrepo.managed:
    - ppa: rael-gc/rvm
  pkg.installed:
    - name: rvm
    - require:
      - pkgrepo: rvm

ruby-3.1.2:
  rvm.installed

Describe the solution you'd like
Salt to detect rvm is installed under /usr/share/rvm/bin/rvm.

Describe alternatives you've considered
I also considered making the rvm binary path a variable you can pass to states however this is a much bigger change.

Additional context

Start in salt/modules/rvm.py around the referenced line 68 and inspect how the RVM binary path is determined. Reproduce the provided Salt states with the apt-installed package, then verify that the existing /usr/share/rvm/bin/rvm installation is detected instead of being installed again.
