[FEATURE_REQUEST] Add guidance on VM SKUs to setup instructions

[mawah]

Description

In the setup guide, users may need more guidance on what SKU to select. From experience I know which VMs have GPUs, and how to request more quota if I find I can’t create a VM, but your repo users might not know those things. But even so, I'm unsure what type of VM to create, because at this point I know very little of CVBP e.g. whether there is any point having more than one GPU (can CVBP handle distributed training?), whether there are features I will miss out on if I use a Windows vs. Ubuntu DSVM, etc.

Expected behavior with the suggested feature

See above.
