Bug: Pydantic deprecated methods are still used

[ascopes]

Expected Behaviour

Deprecated APIs should not be used.

Current Behaviour

/path/to/my/project/.venv/lib/python3.12/site-packages/pydantic/main.py:1132: PydanticDeprecatedSince20: The `parse_obj` method is deprecated; use `model_validate` instead. Deprecated in Pydantic V2.0 to be removed in V3.0. See Pydantic V2 Migration Guide at https://errors.pydantic.dev/2.8/migration/
    warnings.warn(
-- Docs: https://docs.pytest.org/en/stable/how-to/capture-warnings.html

Code snippet

from aws_lambda_powertools.utilities.parser import event_parser
from aws_lambda_powertools.utilities.typing import LambdaContext
from pydantic import BaseModel

class Ping(BaseModel):
    message: str


@event_parser(model=Ping)
def lambda_handler(event: Ping, _: LambdaContext) -> None:
    print(event.message)

Possible Solution

Update aws_lambda_powertools internals to use model_validate rather than parse_obj if Pydantic v2 is in use.

Hi @ascopes! Thanks for opening this issue! Yes, we are aware of this and are about to release the major version of Powertools - V3, where we will remove Pydantic v1 and only support Pydantic v2 with non-deprecated methods.
