chore(validate): drop the game checks left over from the catalog split

Games moved to the game-catalog repository and data/game no longer
exists, so GAME_REQUIRED and the loop over an always-empty list checked
nothing. The engine's validator has no game branch either.

The docstring named a validate-data.yml workflow this repo does not
have; it now names what runs the validator and says which document the
section numbers in the messages belong to. A comment cited a decision
record that is about something else. No check changes: the full scan
passes as before. Line endings are untouched (still CRLF).
