change: Detect and show pydantic ClassVar attibutes

[mmzeynalli]

Is your change request related to a problem? Please describe.

If I have:

from pydantic import BaseModel
from pydantic.alias_generators import to_pascal

class BaseRequestSchema(BaseModel):
    model_config = ConfigDict(alias_generator=AliasGenerator(serialization_alias=to_pascal))

    URL_PARAM_FIELDS: ClassVar[list[str]]

    merchant: str

I get doc like:

Even if model_config is parsed differently (as it should), URL_PARAM_FIELDS is showing label of pydantic-field. However, it is not considered a pydantic field and is not validated/serialized as part of process.

Describe the solution you'd like

To show in the docs as ClassVar instead of pydantic-field

Describe alternatives you've considered

Kinda related to #18.

Yes, missed that one to be honest. Considering it is the same, I am closing this one.
