v2.0.0

The script has been rewritten in TypeScript, because the original 1.0.x version was getting too big and tough to maintain.
It does not require any dependencies (excluding the dev ones, which are not present in the final build).

Changelog

• the code was refactored and split up into multiple files
• the script is built using esbuild
• the "translated articles" list was replaced by a table
• info about translated articles is not being cached (for now)
• the translated articles scanner is now using the MediaWiki API instead of parsing raw contents of pages - speeding it up by a lot
• caching and settings are now handled by IndexedDB (not by localStorage)
• missing language infos were added
