Add CLI authentication commands documentation

[mintlify]

Summary

• Documents the mint login, mint status, and mint logout CLI commands, which are now visible user-facing commands
• Adds an "Authentication" section to the CLI page explaining how to authenticate with Mintlify from the terminal

What shipped

The CLI now exposes mint login, mint status, and mint logout as visible commands. The login flow opens a browser for OAuth authentication and can receive the authorization code automatically from the dashboard, with a manual paste fallback.

Note

Low Risk
Low risk documentation-only change adding usage guidance for CLI authentication commands and updating page metadata.

Overview
Adds CLI authentication documentation to installation.mdx, introducing a new Authentication section with instructions for mint login, mint status, and mint logout (including a brief description of the browser-based login flow and manual fallback).

Updates the page keywords to include the new authentication-related terms for discoverability.
