Update CODEOWNERS to use a mapping team for maps

[PowerfulBacon]

About The Pull Request

Updates code-owners so that it works by using a team instead of an individual person.

Why It's Good For The Game

More flexability and the use of teams allows for setting up specific rules per-group (mappers can only merge mapping changes, as an example).

(mappers can only merge mapping changes, as an example).

Seems like a good way to manage permissions without as much oversight.

Only question, for sprite/maptainers like pigeon, generally it's been fine for them to approve and merge icon/map changes, but if a pr has a single code change (like changing icon_state = "meat" to icon_state = "meatsteak"), would he no longer be able to merge it?

Code owners isn't a determination for who can merge something, it just expresses responsibility for portions of the repository.
