[bug#62664] [PATCH] [WIP] gnu: Add emacs-copilot.

[Rostislav Svoboda <rostislav.svoboda@gmail.com>]

As hinted in the commit message, this patch is Work-In-Progress,
waiting for Node v16+ to become available as a Guix package. I.e. this
patch is not ready for integration in the upstream, yet
However I assume some folks may benefit from it, anyway.

Cheers Bost
