Fixed Username regular expression match description

[Liam W]

Affected version

2.0.0 Beta 5

In the username regular expression match option, it doesn't take a full regex with modifiers, but it doesn't tell us anything about this, hence my regex failing and stopping anyone from registering.

Maybe either add a note to the explanation or allow a full regex?

FWIW, it is probably better to move the full regex and modifiers into the option as that would allow case sensitivity options to be controlled more easily, though to do this we do need to be careful migrating existing values.
