Update to Python 3.13 for RTD builds when available

[funkyfuture]

So I did some digging and the website itself still uses the _ for deck-chores.daily_job.command but the usage.rst does not.

Would you be able to push the changes to the RTD to reflect your already committed changes after merging #147?

this is currently blocked by: readthedocs/readthedocs.org#11671

when unblocked, i shall then switch to the single-version-option and possibly make main the default version.

Is it possible to use Python 3.12 for now until they fix the 3.13 support in the upcoming months?

[funkyfuture]

you're right. would you be so kind to open a PR that lowers the required Python version to 3.12 for the RTD build and the package metadata with accompanying # TODO hints to this issue. that should suffice from the top of my head.

[funkyfuture]

okay, eventually it works. please verify that it "works for you".

The website https://deck-chores.readthedocs.io/ works for me! Thanks for changing the requirements.txt and adding the # TODO I missed
