Correctly describe the serialization format in the JSON schema

[multimeric]

Currently, an Np1DArrayFp64 will generate a JSON schema with the following type:

"type": "np.ndarray[tuple[int], np.dtype[float64]"

This is incorrect, as I don't think it's a valid JSON schema type at all. What it should return is the JSON schema describing a NumpyDataDict, which is already in the repo:

pydantic-numpy/pydantic_numpy/helper/typing.py

Lines 7 to 9 in 438b18c

	class NumpyDataDict(TypedDict):
	data_type: str
	data: list

Here's a reproducible example:

>>> from pydantic.type_adapter import TypeAdapter
>>> from pydantic_numpy.typing import Np1DArrayFp64
>>> TypeAdapter(Np1DArrayFp64).json_schema()
{'strict_data_typing': False, 'type': 'np.ndarray[tuple[int], np.dtype[float64]'}

Are you open to a PR fixing this? Because it's moderately important to my use case.

I will fix it, but it will have to wait till April. Welcome to make a PR if you can't wait in the meantime.
