Subject: [PATCH] fix(zammad): fix Elasticsearch JVM config and add
 daemon-reload (#12125)

The JVM heap options were appended with >> which left the old
defaults in place. Use sed to replace them instead.
Also add the missing systemctl daemon-reload that ES requires
after package installation before the service can be started.

Closes #12111
