[IDEA] Request to Update Documentation and Enhance Local Setup Options for Emacs Client

[Cletip]

Hello everyone,

Thank you for the excellent Khoj package, it's truly superb! However, I've encountered an issue while setting it up in Emacs.

According to the current documentation available at https://docs.khoj.dev/clients/emacs#setup, an API key is required to use the client. I am interested in a fully local solution and would prefer not to use an API key.
In previous versions, it was possible to set up everything locally using the khoj-server-url variable to point to a localhost adress. This was very convenient because the khoj command would set up everything automatically, and I didn't have to do much to get it up and running.

Could you please consider updating the documentation to include information on how to set up Khoj locally without needing an external server? Is there something that I missed ?

Thank you for your attention to this matter.
