Support international emails: Add regex support for . with negation

[Divide-By-0]

I think our regex circom circuit should support "." (all characters except for a new line) and a negation regex.
For example, they are important to support users in non-English countries because their gmail account names usually includes non-alphabet characters.
If we can "." and the negation regex, we can accept any bytes except for ">" as the string of the user name.
