docs: add CLI configuration details and fix CLI documentation navigation

Description:

• This PR closes ADD : CMD doesn't have the documentation #2428.
• The documentation was already present but wasn't displaying on the website due to a navigation.js misconfiguration, and hence a 404 not found page is displayed [image attached].
• Further, the documentation didn't include the CMD_LOGS_FILE configurable environment variable.

Breaking Changes (if applicable):

• No Breaking changes

Additional Information:

• Moved the cli docs from docs/cli to docs/quick-start/cli and updated navigation.js with the path ref.
