local_docker scheduler unable to set gpu correctly

[ryxli]

🐛 Bug

Device Request capabilities should be updated to "gpu", not "compute"
https://github.com/pytorch/torchx/blob/main/torchx/schedulers/docker_scheduler.py#L308

                    c.kwargs["device_requests"] = [
                        DeviceRequest(
                            count=resource.gpu,
                            capabilities=[["compute"]],
                        )
                    ]

Module (check all that applies):

• torchx.spec
• torchx.component
• torchx.apps
• torchx.runtime
• torchx.cli
• [ x] torchx.schedulers
• torchx.pipelines
• torchx.aws
• torchx.examples
• other

To Reproduce

Steps to reproduce the behavior:

1. start any container with local_docker scheduler on a machine with nvidia gpu
2. run nvidia-smi inside container to verify that container does not detect gpu

pretrain/0 Failed to detect NVIDIA driver version.

Expected behavior

if device capability is properly set to "gpu", then i should see devices inside container and can detect nvidia driver

after changing "compute" to "gpu", works as expected
