Description

I ended up updating some code that I wrote for Invidious to find locales that use incorrect template strings/are missing template strings. https://github.com/iv-org/invidious/issues/1951#issuecomment-1947659377

This should make finding issues with other locales a lot easier

Ideally we would upstream some of this functionality into vue-i18n-eslint

Testing

• yarn run checkforbadtemplates should create a locale-errors.json file at the root of the project as well as log the errors to the console. I didn't fix every issue as some of them aren't that straightforward without knowing the language that is being translated.
