Class based resources moved from ember-resource to ember-modify-based-class-resource

[cah-brian-gantzler]

Class based resources have been moved from ember-resource to https://github.com/NullVoxPopuli/ember-modify-based-class-resource/. There is a deprecation being thrown for anyone updating to ember-resources version 7. This addon uses class based resources at https://github.com/simonihmig/ember-stargate/blob/master/ember-stargate/src/components/portal.ts#L13. See https://github.com/NullVoxPopuli/ember-resources/blob/main/MIGRATIONS.md#70
