The problem:
If there is an article in English version and not in e.g. Polish, the bot will find the article in English and send the link without localization (thus it can be opened as a Polish version) and it will show the error on the page.
Link for searching: https://github.com/typeofweb/typeofweb-discord-bot/blob/main/src/commands/mdn.ts#L11
Link that is sent: https://github.com/typeofweb/typeofweb-discord-bot/blob/main/src/commands/mdn.ts#L21
Suggested solution:
Add en-US localization to the sent URL, so it always redirects to the English version of MDN
Test search phrase: Promise.allSettled (available in EN, unavailable in PL)
