docs: Change factuality and word choice in app.runningUnderARM64Translation (#36947)
Change factuality and word choice.
Added "or WOW" to the phrase, "when they are running the x64 version under Rosetta", to reflect the use of a supported platform, Windows, as a possible scenario.
Changed the wording of that same sentence to make it appear clearer. "incorrectly" to "mistakenly" and moved this word to before the verb instead of the end of the sentence.
