Example Code

from sqlmodel import Field

# This should work, according to Pydantic docs
class PydanticHero(SQLModel):
    foo: str = Field(json_schema_extra={ 'enum': ["some", "values"})

# This currently does work as a hacky workaround
class SQLModelHero(SQLModel):
    foo: str = Field(schema_extra={"json_schema_extra":{ 'enum': ["some", "values"}})

Description

I've got a case where I want to set some valid enum values in a schema, and this should be doable with json_schema_extra. Except it's a Pydantic v2 feature, and SQLModel only seems to support the v1 version (see also https://docs.pydantic.dev/latest/migration/#changes-to-pydanticfield). I found a hacky workaround (see example), but it's kinda terrible

I have some other uses for json_schema_extra, and right now this is preventing me from moving forward with SQLModel... :(
