Add Python 3.12 build

[offa]

First steps to support to support Python 3.12.

There's a build failure on Ubuntu though:

   Traceback (most recent call last):

The tests passed in my own environment. I will do some more debugging.

Any progress then?

[tan-wei]

The failure seems not related to the test. Re-run CI may become pass.

[offa]

I still get the same error on replay unfortunately. But it may be fixed by typing extensions >= 4.7.0 (4.4.0 is used at the moment).

This seems to fix the Python 3.12 build 🎉. Python 3.7 is broken now though:

Python 3.8 or above is required to install PDM.

[offa]

Given Python 3.7 is EOL, I suggest removing it.

This needs an update of the projects CI settings too (3.7 is still required, but 3.12 not).

[tan-wei]

Good news!

[regen100]

Thank you for your PR. Dropping 3.7 support is reasonable.
