Chown workspace in calculate-docker-image (#58398)
Summary:
Since https://github.com/pytorch/pytorch/issues/58299 changed the calculate-docker-image job from `ubuntu-18.04` to `linux.2xlarge`, it has been sometimes failing with this message:
```
Warning: Unable to clean or reset the repository. The repository will be recreated instead.
Deleting the contents of '/home/ec2-user/actions-runner/_work/pytorch/pytorch'
Error: Command failed: rm -rf "/home/ec2-user/actions-runner/_work/pytorch/pytorch/.azure_pipelines"

This PR hopes to fix that issue by adding the "Chown workspace" step that we already use for the other jobs in the Linux CI workflow.
