Improves the regular expressions for email validation to correctly handle email addresses with multiple domain levels (subdomains). The previous regex only supported single-level domains like example.com, while the new pattern properly validates addresses like user@mail.example.com. This change follows RFC 5322 standards for email addresses and maintains backward compatibility with existing valid addresses

Thanks. I tested the existing script and found that it already accepts email addresses with one or multiple subdomains. I also found that there are already several email addresses that follow the described pattern in the repository (e.g., karljohan-alm@garage.co.jp, rusty@rustcorp.com.au, and aj@erisian.com.au).

Therefore, the motivation for this pull request is unsubstantiated and the change unnecessary.
