Request to allow users to edit Workspaces OAuth Token scopes to enable PostStart command block execution
<!-- This template is a great use for issues that are feature::additions or technical tasks for larger issues.-->
### Proposal
Using GitLab Workspaces with pre-built private images result in the commands under the `postStart` script block to not execute properly or consistently. This is due to the Workspaces OAuth token not the having sufficient scope (`read_registry`) to pull images from private container registries:
```bash
Example devfile change:
# Before (failed with ImagePullBackOff):
image: "<PRIVATE_REGISTRY_URL>:5050/my-group/my-project:latest"
# After (works):
image: "registry.gitlab.com/gitlab-org/gitlab-build-images/workspaces/ubuntu-24.04:..."
events:
postStart:
- install-deps # pip install at runtime
```
Using public GitLab workspace base images properly execute commands in the `postStart` block.
However, we would like the ability for those using Self-Managed instances and using private registries to be able to modify or add the `read_registry` scope to the Workspaces OAuth token.
Including this feature allows for users to use the commands in the `postStart` block and introduces flexibility for those that are using GitLab Workspaces with images from private container registries.
