ci: pre-pull Testcontainers images in worker before unit tests (#19464)
(#19465)
Fixes #19464.
Once the image is in the runner's local Docker daemon cache, KafkaContainer
start in KafkaResource becomes a pure container-spinup (~5-15 s) instead of
pull+spinup (~30-90 s + Docker Hub variance). The 60 s LatchableEmitter wall
now has 4-12× more headroom.
