[Feature Request]: Add documentation for last.fm login #2115

Preflight Checklist

• I use the latest version of YouTube Music (Application).
• I have searched the issue tracker for a feature request that matches the one I want to file, without success.

Problem Description

The standard window that opens showing api keys is pretty confusing for a new user, it should be better documented that you can right click to open the login page.

Proposed Solution

Better document the ability to right-click on the API settings to open a login window.

Alternatives Considered

Make it default behavior, add a separate button to login.
