[Feature Request] Support Markdown in CLI help output in terminal

[yuandrew]

Is your feature request related to a problem? Please describe.

Describe the solution you'd like

It may be tricky figuring out how to support all types of terminals. We need to ensure the older terminals with minimal functionality can support this feature.
