teamGameSpawnAreas for Baikal ⚡ (#3467)

## Description:

"Baikal (Nuke Wars)" has teamGameSpawnAreas (for Random Spawn), but
Baikal not. Because teamGameSpawnAreas was intended for a "Nuke Wars"
modifier. Let's add teamGameSpawnAreas also to Baikal to improve random
spawning (special rotation) a bit (until we have a better random spawn
algo).

## 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:
