CI: Make having a "language pack" for Hotcakes a reality

[WillStrohl]

Hotcakes Commerce is almost fully localizable, but due to its current architecture, it lacks the ability to have a specific language pack. Right now, it requires languages to be included with its respective viewset(s) and another language pack for the module itself.

I don't expect for this architecture to change. Viewsets and the core solution should be different when it comes to languages.

However, there needs to be language packs created for:

• Spanish
• German
• Dutch
• Italian
• French

There could be more, but these are the most common languages that should be supported, in addition to English.
