[FAB-8602] Add volumes to first-network e2e yaml

The first-network CLI yaml was recently enhanced to use volume mounts
for the ledger directories.  There is the additional e2e yaml which
depends on the container definitions and is now failing.  This CR simply
edits its template to include these new volume definitions.
