Add watch task for yarn generate-translations

[henrytao-me]

What

Currently, we need to run yarn generate-translations every time we change translations folder src/locale/translations/ and commit the compiled file. It would be better to:

• Add a watch task to automatically generate it.
• Ignore compiled file on git to prevent PR conflicts.

I am going to take a crack at this following this tutorial: https://flaviocopes.com/package-json-watch/

Is this example what you were thinking of?

That's the way to go. Go for it. 🙇

I will leave the translation issues to you then @ChrisDryden. Thanks so much. I will take the bluetooth one.
