release-26.3: roachtest: replicagc-changed-peers/restart=false failed

**Note:** This build has runtime assertions enabled. If the same failure was hit in a run without assertions enabled, there should be a similar failure without this message. If there isn't one, then this failure is likely due to an assertion violation or (assertion) timeout.

Jira issue: CRDB-64946

Start with pkg/cmd/roachtest/replicagc.go at line 96 and inspect the failed run artifacts and logs under /artifacts/replicagc-changed-peers/restart=false/run_1. Read the roachtest README and compare the runtime-assertions failure with the linked TeamCity and observability reports. Done means identifying the cause of the failed test and providing a verified fix or a clearly documented test/report change.
