[BUG] Role model updates

[takos22]

The UpdateRoleBody and NewRoleBody have some issues and need some updates, here are the needed updates:

1. The UpdateRoleBody.name has a max_length of 64 instead of the 32 in NewRoleBody.name.
   

   API/api/versions/v1/routers/roles/models.py

   Line 24 in 261ecd3

   name: str = Field("", min_length=4, max_length=64)

2. The NewRoleBody.color and UpdateRoleBody.color could use a pydantic.Color field instead of the current int field.
