Test Python 3.12-dev

[hugovk]

Python 3.12 will be in beta in May, which is when third-party projects should start testing it in advance of the October release.

The reason for this is three-fold:

• Find 3.12 incompatibilities in this library and fix them in time
• Find bugs in Python itself, to report them upstream and fix them for everyone
• Allow other libraries that depend on this one, to install and test 3.12

Probably you can also update https://github.com/jazzband/geojson/blob/main/tox.ini to support 3.12. But, I'm not sure where it's used.

[hugovk]

Thanks, updated! It's used for when you run tox without specifying the env (e.g. so not tox -e py39), and it'll run on all those listed.

~Or I've pushed https://github.com/hugovk/geojson/commit/9c927d39ce96fd689e8f8fa72891d3ee17493668 to the branch https://github.com/hugovk/geojson/commits/test-3.12-dev/ but it's not showing up here https://github.com/jazzband/geojson/pull/211/commits yet...~

Edit: it's fine now.
