Remove use of distuitls as deprecated and breaking use in Python 3.12

As noted in https://github.com/proycon/codemetapy/commit/71938e0f203bcc03e84a999a34b77d3e94caac0a

https://github.com/proycon/codemetapy/blob/b904d74a3d1739b15168e12fdd3114e4359f639c/codemeta/codemeta.py#L18

distuitls has been deprecated and removed from Python 3.12, so codemetapy now breaks in Python 3.12 (c.f. https://github.com/xrootd/xrootd/issues/1698 for some other info from another project).

Example:

Using pipx only as this is how many people will do so to get a command line utility

root@62201609b254:/# python --version
Python 3.12.3
$ docker run --rm -ti python:3.12 /bin/bash
root@62201609b254:/# python -m pip --quiet install --upgrade pipx
WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venv
root@62201609b254:/# pipx ensurepath
Success! Added /root/.local/bin to the PATH environment variable.

Consider adding shell completions for pipx. Run 'pipx completions' for instructions.

You will need to open a new terminal or re-login for the PATH changes to take effect.

Otherwise pipx is ready to go! ✨ 🌟 ✨
