docs: update sendmail docs to use more secure SMTP server for Gmail
Earlier recommendation by IETF with RFC 2595 was to deprecate implicit TLS in preference for upgrade an initially unencrypted connection with STARTTLS command. These days, however, IETF recommends that connections be made using "Implicit TLS", in preference to STARTTLS and the like, completely reversing their earlier position, in RFC8314. Update the GMail example to use the implicit TLS to match the current recommendation at port 465. Signed-off-by: Aditya Garg <gargaditya08@live.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
