📝 Walkthrough

Walkthrough

This pull request updates Redpanda documentation configuration and property references for version v25.3.3. The changes include: updates to antora.yml with version bumps (latest-redpanda-tag from v25.3.1 to v25.3.3), normalization of YAML formatting (quote removal, indentation adjustments), date format updates to ISO 8601 timestamp, and reformatting of home page content with adjusted line wrapping. Additionally, six new cluster properties are added to the property reference documentation: cloud_topics_epoch_service_epoch_increment_interval, cloud_topics_epoch_service_local_epoch_cache_duration, cloud_topics_short_term_gc_backoff_interval, cloud_topics_short_term_gc_interval, cloud_topics_short_term_gc_minimum_object_age, and fetch_max_read_concurrency, with corresponding metadata and descriptions documented in AsciiDoc.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

• Version number consistency: verify v25.3.3 is correctly applied across all references
• Property metadata accuracy: confirm that all new properties have correct types, defaults, and descriptions in both the JSON data file and AsciiDoc documentation
• YAML formatting consistency: ensure quote removal and indentation changes are applied uniformly and do not introduce syntax errors
• Home page content integrity: validate that content reflowing in page-home-intro and related home sections preserves readability and intended meanings
