The other 3 possibilities are:

1-Menagerie is not an official, recognized kingdom, thus why it isn't recognized in the festival. The same happens in Real Life in the UN.

2-It's a recognized state, but less of a "Sovereign" and more of an "Observer", like the Vatican or the Order of Malta.

3-The Vytal Festival and the Colosseum were made after the Great War between the 4 kingdoms. It happened before the FRR. So 2 things happen: 1) Faunus Discrimination was still popular, and 2) The festival would acknowledge more the kingdoms whose peace between created it, than Menagerie who apparently wasn't involved too much.
