.builds/static.yml: upgrade Alpine

Add a section on cover letters

Rephrase confusing password bit

The local SMTP version doesn't prompt for a password and that's the
one I have (I was already using msmtp for something else) so when I
first read this part I got mega confused, thinking "whaddayamean
password?"

Update local SMTP client config for sendemail.sendmailCmd

Add OpenMandriva

Add missing 'is'

Fixes: 31692ee6 ("Initial commit")

Change Fastmail config to use implicit TLS instead of STARTTLS.

Fastmail supports implicit TLS so there is no reason to use STARTTLS.

Add Rocky Linux

Add missing styles for Fastmail accordion

Note systems with sendmail setup needn't be configured

Make Nix install instructions fully comprehensive

Added Fastmail config info

Fix meaning of "Sign off"

Use direct TLS by default, add hints for STARTTLS

In general it's better to use direct TLS connections. Default to
direct TLS in our example Git config.

Add a hint about STARTTLS, because (1) some old providers may still
not have direct TLS and (2) the Git smtpencryption option is very
confusing.

Bump Alpine version

Ditch pystache
