new 6f15d58ae6f MINOR: Fix broken documentation links for Streams
Rebalance Protocol (#21685)
6f15d58ae6f is described below
commit 6f15d58ae6f5e3cb70e55bbc917b67eea520993c

MINOR: Fix broken documentation links for Streams Rebalance Protocol
(#21685)
Fix internal documentation links that were using the old path format
(`/documentation/streams/...`) and `.html` extensions, which no longer
resolve correctly in the new docs site structure. Also reorder the
KAFKA-20254 migration warning note in the Streams upgrade guide to
appear after the GA announcement paragraph for better readability.
