In commit 4812a57f, the fmt-based formatter for gossip_digest_syn had
formatting code for cluster_id, partitioner, and group0_id
accidentally commented out, preventing these fields from being included
in the output. This commit restores the formatting by uncommenting the
code, ensuring full visibility of all fields in the gossip_digest_syn
message when logging permits.
This fixes a regression introduced in 4812a57f, which obscured these
fields and reduced debugging insight. Backporting is recommended for
improved observability.
