`registerUnbound` was present for legacy reasons when using helpers in raw-hbs and has been replaced by `registerRawHelper`.
For new helpers used only in classic ember template, exporting a default function from `helpers/*.js` is recommended.
This change also means that all existing helpers will be available to import in `gjs` files.

version of Discourse everything should be the same as before, just with
a few extra files that are not used. However, using Ember CLI this can
be installed as an Ember addon.
