docker-compose-buildkite-plugin cache issues

Context

We noticed a bunch of issues related to cache hits when using the docker-compose-buildkite-plugin to do docker builds.

List of things found

1. There is (was?) a bug in moby/buildkite where using --cache-from was only getting cache hits on every second build
2. The above bug was fixed in 2024 but this fix has not yet made it into the buildkite elastic-ci-stack OSS CI stack
