mypy: pa.typing.Series does not support pd.DatetimeTZDtype as a type argument

[DXsmiley]

Describe the bug

Under mypy, pa.typing.Series does not support pd.DatetimeTZDtype as a valid type argument.

Bug occurs with and without pandera.mypy plugin

• I have checked that this issue has not already been reported.
• I have confirmed this bug exists on the latest version of pandera.
• (optional) I have confirmed this bug exists on the master branch of pandera.

Code Sample, a copy-pastable example

from typing import Annotated
import pandas as pd
import pandera as pa
from pandera.typing import Series

class MySchema(pa.SchemaModel):
    # both lines taken from the pandera documentation
    a: Series[Annotated[pd.DatetimeTZDtype, "ns", "UTC"]]
    b: Series[pd.DatetimeTZDtype] = pa.Field(dtype_kwargs={"unit": "ns", "tz": "UTC"})

Expected behavior

mypy should show no errors

Actual behaviour

mypy produces the following errors

test.py:8: error: Value of type variable "GenericDtype" of "Series" cannot be "DatetimeTZDtype"
test.py:9: error: Value of type variable "GenericDtype" of "Series" cannot be "DatetimeTZDtype"

Versions

pandas==1.5.0
pandas-stubs==1.4.3.220807
pandera==0.13.3
mypy==0.982
mypy-extensions==0.4.3
