[Bug]: DeprecationWarning due to use of general_plain_validator_function in MSONable.__get_pydantic_core_schema__ with Pydantic v2

[ugognw]

monty/monty/json.py

Lines 291 to 300 in 5d37679

	def __get_pydantic_core_schema__(cls, source_type, handler):
	"""
	pydantic v2 core schema definition
	"""
	if core_schema is None:
	raise RuntimeError("Pydantic >= 2.0 is required for validation")
	s = core_schema.general_plain_validator_function(cls.validate_monty_v2)
	return core_schema.json_or_python_schema(json_schema=s, python_schema=s)

Pydantic suggests a straight swap for core_schema.with_info_plain_validator_function
