Fix kinematic tree bug that breaks SMPLH loading

[MarilynKeller]

In the current version, the SMPLH model is not loading anymore. This is caused by a change hat was made in the MANO commit:
https://github.com/MarilynKeller/aitviewer/blob/8fb6d4661303579ef04b3bf63ac907dbaecff2ff/aitviewer/renderables/smpl.py#L162C71-L162C86

In the previous version, only the body pose parameters would be passed here, not the hands. skeleton only contains the body skeleton, hence the crash.

I reverted this change such that only the root orientation and the body pose are passed.

The propose fix does not change the behavior with MANO.

Also, note that I am on python 3.12.3 and it is running with "moderngl-window==2.4.6". Setup.py currently limits the python version to < 3.11.

It seems like the workflow is failing because Python 3.7 is not available on Ubuntu 24.04, which is used by ubuntu-latest runners. I believe the workflow should be upgraded to at least python 3.8. (which my last commit do)

Hey @MarilynKeller I've also faced the same issue, and I tried to fix it with this. It is similar in essence, but also fixes the skeleton loading and keeps the option to use smplx or smplh model with articulated hands.

I think your version results in displaying the SMPLH joints for each hand joint right? I was hesitant to do so as well as the result visual is a bit cluttered. Maybe ideal would be an additional parameter to the sequence to control or not to display the hands.
