Bugfix: Commas are incorrectly allowed in email regex.

[mokemoko]

In #2824, email regex changed, but it seems inadvertently allowed , which were previously not permitted in email.

Email regex before #2824

/^([A-Z0-9_+-]+\.?)*[A-Z0-9_+-]@([A-Z0-9][A-Z0-9\-]*\.)+[A-Z]{2,}$/i;

Email regex after #2824

/^(?!\.)(?!.*\.\.)([A-Z0-9_+-\.]*)[A-Z0-9_+-]@([A-Z0-9][A-Z0-9\-]*\.)+[A-Z]{2,}$/i;

For the latter part [A-Z0-9_+-\.], it probably wanted to add only . to [A-Z0-9_+-]. But, the addition of . after the unescaped hyphen has caused it to be interpreted as a range from + to .. Therefore, , contained between + and . is now permitted.

So, fix this issue with escaping hyphens simply.

Thank you! Fantastic PR, apologies for the delay on such a no-brainer PR. That accidental range issue could have been a lot worse lol.
