Cannot install under Python 3.11 due to failure building LXML

[Evolution0]

Describe the bug/problem
Cannot install under Python 3.11 due to being unable to build LXML 4.8.0 with Python 3.11.

To Reproduce
Steps to reproduce the behavior:

1. Attempt to install under Python 3.11

Environment (please complete the following information):

• OS: Windows 10
• Python version: Python 3.11
• Calibre-Web version: 0.6.19
• Docker container: None
• Special Hardware: N/A
• Browser: N/A

Additional context
This is an issue for a lot of projects under Python 3.11 that make use of LXML, its possible to get wheels of 4.9.0 for Python 3.11 even if I can't build it but not 4.8.0 (At least I could not) but calibre-web specifically is set to reject 4.9.0 as an option, is there a particular reason for that?

Switching to a 3.10 venv just as a sanity check and to confirm its not an issue with my system I can indeed install it without a problem, likely I will end up installing in a docker container in the meantime.

I limit the max versions of everything, because in the past some updates had breaking changes, so I‘d like to check it, before I allow it. In this case I don‘t expect any problems, so please try it

At moment, the workaround is using a virtual environment with python3.8 and install calibreweb.

I download the whl file (for my pc architecture), open a cdm in downloads folder and install:
pip install lxml-4.9.0-cp311-cp311-win_amd64.whl
That's work for me.

Yeah at the time the cp311 wheel wasn't available, ~gohlke is what I usually use when I need a wheel of it.
