[feature] New Languages Support

[bpevs]

List of languages we still need to support. Leave a comment here if there's one you want to add! Currently, our only limitation is Translation and TTS (text-to-speech) audio generation; Although it's possible to make a set without automated translation/TTS by having a super-dedicated person, we probably should have an automated way of adding new words. So for now, sticking to list of languages supported by both Azure translation (or DeepL) and Azure TTS

• [x] Afrikaans
• [x] Arabic
• [x] Catalan
• [x] Cantonese
• [x] Hebrew
• [x] Hindi
• [x] Persian
• [x] Spanish (Mexico)
• [x] Thai
• [x] Vietnamese

Azure translation is added in #16. We should now be able to add most of these languages fairly easily.

~Trying to add Arabic, it looked like Azure translation was chopping the first line of the note translations ("dog"). This could be an rtl issue?~ figured out issue. working on now.
