Add games rating

[easysugar]

I didn't find official ratings for the games, so I've added unofficial ratings.
Example:

Where do these unofficial ratings come from?

@spilth Almost the first link in the google https://whatnerd.com/every-jackbox-party-pack-ranked/. But it's possible to change ratings to something else.

@easysugar I definitely appreciate the PRs you've been making. I think it would be good to start making Issues for functionality first so they can be discussed before folks start spending time on development.

For example, I don't know how valuable reversing the sort order is. I feel like default to alphabetical for names/packs and best to worst for ratings would be what folks want to see. That would mean a less complicated UX and less complicated code.

Agree. But I think that ordering is a must for any sorting. So it should contain the reversing order to be logically completed.
