Add lazy loading of lang files

[geichelberger]

Only the currently used language is loaded instead of all language files from the beginning. A new lazy loading backend loads the lang files as a dynamic import.

This should fix the bug that sometimes the language keys are missing.

Works. Can't really confirm whether this fixes the issue with languages not loading sometimes as I cannot consistently reproduce it, but at the very least it does not break anything obvious :D

That being said, does renaming the locales break our crowdin workflow?

I missed that the locales.json is generated automatically; this also resolves the issues of populating the array. I will change that.

I changed how the crowdin translation array/map is generated by replacing the locales.json with an lngs-generated.ts file. The locales now have the same name as before, and the generation script creates a map of the country codes and the languages.

Can't really test this, but in general this looks solid to me (if maybe a little convoluted, but that's more i18ns fault than anything).

I changed the script path to use the absolute path with $GITHUB_WORKFLOW because the action uses a working directory.
