add support for python 3.13

[baywet]

depends on microsoftgraph/msgraph-sdk-python-core#704
Effectively the same for this library

[kamikaze]

this package pulls an abandoned pendulum package:

python-pendulum/pendulum#844

python-pendulum/pendulum#590

[danieleds]

this is currently blocking us from upgrading to Python 3.13.

There maybe is a surprise coming, Kiota no longer needs pendulum. Maybe we see python 3.13 support in January.

@baywet I think we can light up official Python 3.13 support, now that core is released?
Can I contribute to that, or will you do the honors

[baywet]

@svrooij Is this something you'd like to submit a pull request for provided some guidance?

[svrooij]

I think I can 👀.... after 4 months you're all going to get Python 3.13 support for the graph api!!
