[FEATURE] Use `saltstack/salt` proposed `snap` modules to improve support in this formula (replace `cmd.run` states)

[myii]

Use the snap modules from the following Salt PR:

• Port #51625 to master saltstack/salt#56953 (port to master for Add snap package management saltstack/salt#51625).

This will both allow for more features as well as remove the current cmd.run states, to achieve a more robust solution.

As I've discussed in that PR's thread, I've already tested this out and it is working well. I'll provide a PR when have some time available.

This will also close #38.
