Fix extension manifest (host) permissions

Both ways of defining them are equivalent strictly, as per
https://developer.chrome.com/docs/extensions/mv3/match_patterns/, since
the path is always treated as /* (so the three entries were the same and
that's why we could inject to other pages such as /*/profile/*), but
this change makes it clear.
