Create CLI documentation

[moklidia]

Also, please note the update to the CLI documentation (i.e. on GitHub). We currently do not have a https://docs.uffizzi.com/cli page

@gadkins What format should we use for CLI documentation? Can it be just the man format?

For now, instead of creating a CLI documentation page, point users to the CLI repository

For all help commands, change this URL to https://github.com/UffizziCloud/uffizzi_cli

See the preview deployment in this PR for the format to use when adding CLI documentation: #68

Specifically, here is the uffizzi preview command as an example: https://docs-uffizzi-pz5gn1el3-uffizzi.vercel.app/references/cli/preview/
