Remove the blue border around the textarea

[max-nextcloud]

Since nextcloud/server#31584 was merged the text editor has a blue border.

Let's remove it.

Just what's the blue border around the textarea, that shouldn't be there. :)

@jancborchardt This was added on purpose to indicate the keyboard focus better, could you confirm that we shall force-remove it on text?

Yes, I mean this makes sense for general inputs and textareas, but e.g. in Word, Google Docs or apps like that you also don’t have a frame around the entire page. So in Text, this border should not exist.
