LibWeb: Fix crash in HTML encoding detection when handling non-ASCII

Browse source 
The fix here was to stop using StringBuilder::append(char) when told to
append a code point, and switch to StringBuilder::append_code_point(u32)

There's probably a bunch more issues like this, and we should stop using
append(char) in general since it allows building of garbage strings.
