Remove unnecessary newlines from key tooltip

[KoBeWi]

These newlines are applied onto last line of the tooltip and aren't visible (luckily tooltips ignore trailing newlines).
And that aside, they shouldn't be even part of the translated string, but outside, like in the parts above.

The other cases feature trailing newlines as well, except for TYPE_VALUE, might be good to clean all even though the translated string cases are the most critical as they're not just not rendered but affect the translation strings (though not critically)

[KoBeWi]

Ok, I deleted other newlines too.
I originally noticed the invalid strings on Weblate, hence I only handled the translated ones.
