NOISSUE Fix strings

[KatieFrogs]

While localizing the launcher to Polish, I have encountered some issues in the source strings

• Typos
• Casual language, referring to the user as "You"
• Wrong capitalization
• Arguments (%1) not being used
• Not being able to translate URLs (e.g. to change /en-us/ to /pl-pl/)
• Question marks in checkbox labels

This PR fixes some of the strings I had issues with

There is also this mysterious string that just says "Got ", which I assume gets printed into console:
launcher/minecraft/auth/steps/MSAStep.cpp:86

overall really nice cleanup! I just have a couple nitpicks

[phit]

the past tense here is intentional as the account has errored

[KatieFrogs]

"Errored" is not a word that exists in formal language. You have to remember, these words have to be translated into other languages, if words are made up, the translators have to make up their own words as well, which often make even less sense than in the original. The correct form would be "Encountered an error", but there is very little space in the UI to fit such a long string.

errored is very much a real adjective https://en.wiktionary.org/wiki/errored
now you can argue all you want about formal language, but I think that ship has sailed a long time ago in terms of real world usage and at least in German, errored translates perfectly to the adjective fehlerhaft

The correct form would be "Encountered an error"
