Add support for Python 3.12

[Clemo97]

Describe the bug

Open-Source-Quartz-Solar-Forecast is dependent on pv-site-prediction. Some dependencies within pv-site-prediction are out of date and not supported by Python 3.12.

To Reproduce

Steps to reproduce the behavior:

1. Make sure you have Python 3.12 installed and clone Open-Source-Quartz-Solar-Forecast
2. Run pip install quartz-solar-forecast

this is needed for openclimatefix/open-source-quartz-solar-forecast#93

This might need chaning - https://github.com/openclimatefix/pv-site-prediction/blob/main/pyproject.toml#L13

pandas-stubs should now be able to be updated as well: pandas-dev/pandas-stubs#625

@Clemo97 did this work?

It did but unfortunately my computer died before I could push my changes😭 😭, hence why I never made a PR. All that's required is running the "poetry update" commands check poetry docs for that which will fail on some dependencies which you then have to manually adjust their version to one that is compatible to Python 3.12.
Pandas-stubs is just the first dependency that's incompatible but there are more, I found like 3 others.

Ahhh I do hate it when that happens! Okay, I'll have a look into this again now. Thanks for the effort you have put in!
