* mathematica: archive version 11 * mathematica: 11.3.0 -> 12.0.0
Note that this only affects the English version, as I do not have access to the hash for the Japanese version.
For now English (default) and Japanese editions only. Fill out information in `l10ns.nix` to add the other localized editions. Example usage: `mathematica.override { lang = "ja"; }` derives Japanese edition.
