Clean Up: Break Translation Helper Into Parts and Add UTs for It

[pjkaufman]

The translation helper is a utility that should help with translating the Linter into different languages. We need to make sure that the core of the logic works and makes sense. In order to do this and make it maintainable, I would like to do the following:

• Create a folder for the logic for the translation helper rather than having it all be in one file and break it into parts
• Add UTs for the testable parts of the translation helper
• Update documentation to include that you need to run npm run build in order to be able to run npm run translate and add a full example of translating into a language

I have some changes that have been pushed to their own branch. They help reduce the complexity of the translation helper and add some UTs for it. It still needs an addition for the documentation around how to contribute translations for new keys, but once that gets done, I should be good to merge it.
