fix(dogfood/coder): stop docker containers and prune system on shutdown (#17904)

mafredri · web-flow · commit 3dbd4245bead · 2025-05-19T13:23:22.000+03:00
This change adds docker stop and docker system prune to the shutdown script so that it doesn't need to be done by the Docker host which will take a lot longer. This change greatly speeds up workspace destruction: ``` 2025-05-19 12:26:57.046+03:00 docker_container.workspace[0]: Destroying... [id=2685e2f456ba7b280c420219f19ef15384faa52c61ba7c087c7f109ffa6b1bda] 2025-05-19 12:27:07.046+03:00 docker_container.workspace[0]: Still destroying... [10s elapsed] 2025-05-19 12:27:16.734+03:00 docker_container.workspace[0]: Destruction complete after 20s ``` Follow-up for #17110
