Bump promoted-builds optional dependency to 892.vd6219fc0a_efb

892.vd6219fc0a_efb was released 2 years ago.  Over 50% of all
installations of the promoted builds plugin are already using
892.vd6219fc0a_efb or newer.  Those users will see no difference from
this change, since they are already using 892.vd6219fc0a_efb.

Recent Jenkins versions will display broken icons with
older versions of the promoted builds plugin.  Fixed in
jenkinsci/promoted-builds-plugin#170 as part
of 873.v6149db_d64130

https://stats.jenkins.io/pluginversions/promoted-builds.html shows that
892.vd6219fc0a_efb is the second most popular release.  It is second
only to the most recent release, 945.v597f5c6a_d3fd.

A step towards eventually upgrading the promoted-builds optional
dependency that is part of the git plugin.  Attempts to update that
optional dependency have shown consistent failures in the plugin bill
of materials.
