Migrate to Pydantic V2

[tancnle]

Resolves #28

[tancnle]

Annotated is added in Python 3.9 (ref) and hence causes test failures in 3.7 and 3.8 CI pipeline.

[tancnle]

I see, we can get Annotated from typing_extensions module instead of typing.

This method is deprecated in favour of validate_call.

The `validate_arguments` method is deprecated; use `validate_call` instead. Deprecated in Pydantic V2.0 to be removed in V3.0. See Pydantic V2 Migration Guide at https://errors.pydantic.dev/2.5/migration/

@tancnle Thanks for tackling this! ❤️

As Pydantic v2 officially supports only Python 3.9+, I think we also need to drop 3.7 and 3.8. Additionally, we can expand to 3.12, 3.13 and 3.14 (the last one is available from Pydantic v2.12).
Can I make that modification to your branch?

@tancnle I will make that change in another PR so we can move forward with this.
