Update Python Versions

[jkterry1]

Hey,

Could you please update the supported and tested Python versions to the current ones and drop the old once (3.10-3.14, by the time this is done it might be 3.11-3.15)

If a community member could create a PR for this, it'd be greatly appreciate :)

@jkterry1 until PR #578 is sorted out and we do some testing for future mujoco versions, we can't support Python 3.14
