Subject: [PATCH] docker-compose: Start all three databases from
 db-only-migrate

The file left out codeinsights-db, which the backup and restore docs dump, and its copies of pgsql and codeintel-db had drifted from docker-compose.yaml. It now extends all three services from that file.

-# This file contains the pgsql service definition (the primary Sourcegraph database deployment),

-# This file is used for database-only operations such as backup and restore.
+# This file starts only the three databases: pgsql (the primary Sourcegraph database),
+# codeintel-db, and codeinsights-db. No other service runs, so nothing else is connected
