Processing extra fields

[denisart]

Problem

bump-pydantic doesn't change when i using extra fields in pydantic.Field. Simple example:

# my code
from pydantic import BaseModel, Field

class Human(BaseModel):
    name: str = Field(..., min_length=1, some_extra_field="some_extra_field_value")

# expected code
from pydantic import BaseModel, Field

class Human(BaseModel):
    name: str = Field(..., min_length=1, json_schema_extra={"some_extra_field": "some_extra_field_value"})

Plus refactor with running black bump_pydantic

I don't know about the implementation (I'm not familiar enough with LibCST, but achieving what the tests show would be useful! 🤓

[Kludex]

Pydantic can't be a dependency of bump_pydantic.

The test passes because the test suit does have pydantic...
