What's New: Cloud Topics enabled by default (DOC-2309)

[Feediver1]

Summary

Adds the July 2026 What's New entry for DOC-2309: Cloud Topics enabled by default (26.2, Aha S-79).

Why only a What's New entry

The topic page itself is single-sourced from the docs repo, and docs#1786 (DOC-2193, the core twin) already made the 26.2 content cloud-correct: the "Create Cloud Topics" section states no separate cluster property is required, and the pre-26.2 cloud_topics_enabled NOTE is gated ifndef::env-cloud[], so cloud readers never see it. Verified there is no stale enablement text elsewhere in cloud-docs (cloud_topics_enabled was never customer-facing here). The stub at modules/develop/pages/topics/cloud-topics.adoc needs no change.

The entry is inserted below the Terraform entry (not at the top of July) to avoid a merge conflict with #654, which edits the top of the same section.

⚠️ Timing check before merging: the entry claims Cloud Topics need no enablement step — true for clusters on Redpanda 26.2 (self-managed GA'd 2026-07-30). Please confirm the 26.2 Cloud fleet rollout status with product before this lands.

Note: DOC-2309 is assigned to Michele — coordinate before merging.
