Enum-like classes cant be used as dictionary keys

[bruno-f-cruz]

Not sure if there is a different intended use...

To reproduce:

from aind_data_schema_models.platforms import Platform
from pydantic import BaseModel


class Foo(BaseModel):
    platform: dict[Platform.ONE_OF, str]


foo = Foo(platform={Platform.BEHAVIOR: "foo"})
print(foo)

bar = foo.model_dump()
