Bug: Language families for creoles are questionable.

[bittlingmayer]

https://machinetranslate.org/creoles lists 1 language, Sango, but it's only their because Wikipedia lists it like that, even though it's immediate ancestor is a Niger-Congo (non-creole) language.

In fact, this code is meant for creole as an abstract concept, so if we use it, we should only use it as a catch-all for various creoles that may be totally unrelated.

There are roughly 2 possible solutions:

1. Remove it

2. Make crp the ultimate parent of all creoles

Make them all under: https://machinetranslate.org/creoles
Then make the specific families like "English-based creoles" a subfamily of this primary one.

So we could create pages like:

• Niger-Congo based creoles (for Sango)
• Spanish-based creoles
• Dutch-based creoles
  To do that, we need to be able to support families without codes.
