[Bug]: No graceful shutdown when building Packer images

[jvstme]

Steps to reproduce

1. Run the "Build docker & cloud images" GitHub Action. Uncheck "Build docker images" and "Build Nebius images", check "Staging build" and one of the clouds.
2. Wait until the workflow creates a cloud instance as part of "Run packer" job.
3. Cancel the workflow.

Actual behavior

Packer does not perform graceful shutdown, the cloud instance keeps running.

Expected behavior

Packer performs graceful shutdown, the cloud instance is terminated.

Additional information

See the Graceful job termination discussion and specifically the repo from this comment.
