[azure-core] Failing to import in Python 3.11.0b3

[major]

• Package Name: azure-core
• Package Version: 1.23.1
• Operating System: Fedora 37
• Python Version: 3.11.0b3

Describe the bug
Fedora 37 has just updated to Python 3.11.0b3 to prepare for the Python 3.11 final release. However, this has caused issues in azure.core with typed variables:

>>> import azure.core
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.11/site-packages/azure/core/__init__.py", line 30, in <module>
    from ._pipeline_client import PipelineClient
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  File "<frozen abc>", line 106, in __new__
  File "/usr/local/lib/python3.11/typing.py", line 1869, in __init_subclass__
    raise TypeError(f"Some type variables ({s_vars}) are"
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: Some type variables (~HTTPRequestType, ~HTTPResponseType) are not listed in Generic[~HTTPRequestType, ~HTTPResponseType]

To Reproduce
Steps to reproduce the behavior:

1. podman run --rm -it --pull always docker.io/library/python:3.11.0b3 bash
2. In the container, run pip install azure-core
3. In the container, run python and type import azure.core
4. The traceback appears

Expected behavior
I would expect the import of azure.core to work properly as it does under Python 3.10.
