Support for Pendulum

Initial Checks

• I confirm that I'm using Pydantic V2

Description

Attempting to use datetime sources other than (and better than) stdlib results in errors under pydantic 2.0
This is a regression from 1.x

pydantic.errors.PydanticSchemaGenerationError: Unable to generate pydantic-core schema for <class 'pendulum.datetime.DateTime'>. Set `arbitrary_types_allowed=True` in the model_config to ignore this error or implement `__get_pydantic_core_schema__` on your type to fully support it.

Example Code

from pydantic import BaseModel
from pendulum import DateTime

class Example(BaseModel):
    last_modified: DateTime

Hi @theunkn0wn1,

Thanks for reporting this. I think this might make sense as an addition to pydantic-extra-types. We'd certainly consider any PRs supporting this change 👍.

@sydney-runkle opened a PR to add this to pydantic-extra-types.

@theunkn0wn1,

Fantastic! I'm going to move this issue over there :).

Hi, would it be possible to add the Time object as well?
