chore: use crdb 24.3 (#9558)

# Which Problems Are Solved

E2E tests in pipelines started to fail randomly. While debugging it, i
noticed that we use the `latest` tag of cockroach's docker image. They
tagged 25.1 as latest yesterday.

# How the Problems Are Solved

Since we drop support for CRDB with version 3 as there are anyway
multiple issues with various versions, I pinned the docker image tag to
`latest-v24.3`.
