Polish were neglected, that ends now. Flag will be used when it sees a Polish entry in the gamelist.
Fixes https://github.com/PCSX2/pcsx2/issues/9137
Bumps the gamelist cache version from 32 to 33
Adds to enumeration
And make it visible in both gamelist and per-game summary view
Update GameList.cpp
Playable rating was missing which is the most common rating for PCSX2. There are some other issues like the images look bad for star rating and some other stuff. Also resize the compatibility table width a bit.
In reality it will show multiple flags like Korean flag but the flags aren't correct due to the structure in the GameDB actually being the languages more than the actual region.
At least people will have Korean flags and others for now and fix GameDB later as it's still a nightly/development cycle.
Though there are about 30 country flags included for future usage as of now.
