docs: correct RFC specifying email line length

bk2204 · gitster · commit fa29f36d990d · 2018-07-09T10:55:12.000-07:00
The git send-email documentation specifies RFC 2821 (the SMTP RFC) as
providing line length limits, but the specification that restricts line
length to 998 octets is RFC 2822 (the email message format RFC).  Since
RFC 2822 has been obsoleted by RFC 5322, update the text to refer to RFC
5322 instead of RFC 2821.
