Support for jazzy on python 3.12?

[kleinfour]

I use other packages which rely on 3.12, but it seems that ros-jazzy-desktop cannot solve for this version yet.
This is the output from following the standard installation instructions but using python 3.12 to setup the mamba environment:

That's correct, we only build for a single Python version (currently Python 3.11) to reduce maintainer burden. When we do the next rebuild, I'd be happy to bump to Python 3.12 (unless there are objections @wolfv @traversaro?).

If you want to, you could create a PR that changes the Python version to 3.11, and address any potential outdated patches etc.; which would accelerate this process.

Ok for me!
