Can't save a model with a field of type pydantic.AnyUrl

Bug

Can't save a model with a field of type pydantic.AnyUrl.

Current Behavior

from odmantic import Model
from pydantic import AnyUrl

from api.models import db


class User(Model):
    name: str


class UserWithPicture(Model):
    name: str
    picture: AnyUrl


async def test_urls() -> None:
    # saves user as expected
    user = User(name="tom")
    await db.save(user)

    # add a url and it throws an error
    user_with_picture = UserWithPicture(
        name="harry",
        picture="https://picsum.photos/200/300",
    )
    await db.save(user_with_picture)

if __name__ == "__main__":
    import asyncio

    loop = asyncio.get_event_loop()
    loop.run_until_complete(test_urls())

Output:

bson.errors.InvalidDocument: cannot encode object: Url('https://picsum.photos/200/300'), of type: <class 'pydantic_core._pydantic_core.Url'>

Expected behavior

I'm upgrading from pydantic v1/odmantic 0.8.0 to pydantic v2/odmantic 1.0.2. Saving urls was working before the upgrade, and I'd expect it to continue working.
