Quickfix: Disable nations in ranked and change map selection (#2957)

## Description:

Quickfix: Disable nations in ranked and change map selection 

(Lewis wanted these, Australia three times so it occurs more often)

Just a quickfix, we will probably have to improve the map selection
later on, and maybe play on non-compact maps too?

## Please complete the following:

- [X] I have added screenshots for all UI updates
- [X] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [X] I have added relevant tests to the test directory
- [X] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced

## Please put your Discord username so you can be contacted if a bug or
regression is found:
