jade 272db8af1b doc: add release note credits and categories for all the changes in Lix
This does not add missing release notes, and it doesn't do anything
about the profiles feature we would really like to have so we can have
consistent credit.

Improvements

Source location information is now included in error messages more consistently. Given this code:

let
  attr = {foo = "bar";};
  key = {};
in
  attr.${key}

Previously, Nix would show this unhelpful message when attempting to evaluate it:

error:
       … while evaluating an attribute name

       error: value is a set while a string was expected

Now, the error message displays where the problematic value was found:

error:
       … while evaluating an attribute name

         at bad.nix:4:11:

            3|   key = {};
            4| in attr.${key}
             |           ^
            5|

       error: expected a string but found a set: { }
