Revert "gg-jj: init at 0.20.0"

Several confused users have reported that this
package does not work at all, and per the discussion in
<https://github.com/NixOS/nixpkgs/pull/345905>, the contributor who
added it does not appear to have tested its basic functionality at
all before opening a pull request.

That’s not acceptable; we rely on package maintainers to be able
to assess the basic functionality of software and ensuring that a
program can even start up before opening a pull request to package it
is basic due diligence. It’s harmful to have a package that doesn’t
work and lacks a maintainer who can assess whether it works or not,
so we should remove it until both of those can be addressed.

This reverts commit 5eb022fdb22e90467d05e9ce880c0f9f096c08aa.
