ML/AI page needs a rework

[vanderwb]

This page is badly in need of a redo: https://ncar-hpc-docs.readthedocs.io/en/latest/environment-and-software/machine-learning-and-deep-learning/?h=machine#machine-learning-and-deep-learning

The information presented is wrong and out of date. At the very least, a reworked page could not incorrectly state that we provide installs of these libraries, and should probably link to Daniel's repo: https://github.com/NCAR/aiml_gpu_ncar_envs
