[tooling] Publish monitoring repo as PyPI package

[the-glu]

Fix #1398 by publishing the monitoring repo as pypi package.

A few note:

• I didn't tested github workflow as they need a release and a token
• A token is needed and need to be set on the repository
• I had to loose constraint version on python version since requiering an explicit one is 'too tight'.
• I targeted specifc monitoring part to be included. Final version look like that:

Tested in a dedicated venv and seems to be working:

uv add /tmp/monitoring-0.28.1.dev0+ge1602f144.d20260520-py3-none-any.whl
uv run python
Python 3.13.11 (main, Jan 28 2026, 00:01:45) [Clang 21.1.4 ] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from monitoring.monitorlib.geo import Altitude
>>> 
>>> Altitude
<class 'monitoring.monitorlib.geo.Altitude'>

I'm super excited about this as I've thought it would be useful for a while! I'll add the tokens; just one small question.

Apparently I was too hasty in my approval; the hygiene check seems to be a true failure and not a transient false positive.

Yes I forgot to put it in draft, sorry. It should be fixed now.

I had to add some fixes as it's now a package (to prevent it from trying to reinstall monitoring), but this add some warning in some cases (warning: --no-sync has no effect when used outside of a project). I think that could be left for future work as it's just a warning.
