Pydantic V2 deprecation warnings

Hello, thanks for quart-schema!

When encoding a type that pydantic knows about but the default JSON encoder doesn't, some deprecation warnings appear:

PydanticDeprecatedSince20: pydantic_encoder is deprecated, use pydantic_core.to_jsonable_python instead. Deprecated in Pydantic V2.0 to be removed in V3.0. See Pydantic V2 Migration Guide at https://errors.pydantic.dev/2.4/migration/

and

PydanticDeprecatedSince20: pydantic_encoder is deprecated, use BaseModel.model_dump instead. Deprecated in Pydantic V2.0 to be removed in V3.0. See Pydantic V2 Migration Guide at https://errors.pydantic.dev/2.4/migration

The affected code for the first warning seems to be here: https://github.com/pgjones/quart-schema/blob/a2171e82cf20ae070c5471e4ae353a2cb3e55846/src/quart_schema/extension.py#L116

I'm not sure about the second one, the line shows python3.10/site-packages/typing_extensions.py:2360 but that doesn't make a lot of sense.

Code that triggers this:

from http import HTTPStatus
from uuid import UUID

import pytest
import pytest_asyncio

from pydantic import BaseModel
from quart import Quart
from quart_schema import QuartSchema, validate_response

app = Quart(__name__)

QuartSchema(app)

class UUIDResponse(BaseModel):
    uuid: UUID

@app.route("/")
@validate_response(UUIDResponse, HTTPStatus.OK)
async def root() -> tuple[UUIDResponse, int]:
    """Root page."""
    return UUIDResponse(uuid="00000000-0000-0000-0000-000000000000"), HTTPStatus.OK

@pytest.mark.asyncio
async def test_root():
    """Test that the root page loads."""
    r = await app.test_client().get("/")

    assert r.status_code == HTTPStatus.OK

For reference, this was with Python 3.10.12, and pip list says:
