Docs feedback: Update queue groups for Elasticsearch

Problem to solve

The elasticsearch example on the Sidekiq page is incomplete. Although the sidekiq page ought not be the source of truth for elasticsearch best practices, it should still provide best effort recommendations.

Further details

The queue_group for Elasticsearch should include some additional queues: cronjob:elastic_index_bulk_cron,cronjob:update_all_mirrors,elastic_commit_indexer,elastic_indexer

Proposal

1. Update page to provide more accurate information
2. Point users to Elasticsearch docs for source of truth
