Update the public fallback documentation.
Line 60 makes an unset workspace.projectClone.imagePullPolicy resolve to IfNotPresent. apis/controller/v1alpha1/devworkspaceoperatorconfig_types.go:395-407 still states that an unset value uses .config.workspace.imagePullPolicy.

@rohanKanojia, confirmed.
internalConfig starts from defaultConfig, and mergeConfig does not replace ProjectCloneConfig.ImagePullPolicy with an empty value. ResolveConfigForWorkspace also merges an external configuration over internalConfig.
Therefore, workspace.Config.Workspace.ProjectCloneConfig.ImagePullPolicy is always non-empty. The fallback at devworkspace_controller.go:396-398 is unreachable.
This also confirms the documentation finding. The API documentation must not state that project-clone inherits workspace.imagePullPolicy.

Learning: In `pkg/config/sync.go`, `internalConfig` is initialized from `defaultConfig`, and `mergeConfig` only overwrites `WorkspaceConfig.ProjectCloneConfig.ImagePullPolicy` when the incoming value is non-empty. `ResolveConfigForWorkspace` merges external DevWorkspaceOperatorConfig values over `internalConfig`. Therefore, after `pkg/config/defaults.go` sets `ProjectCloneConfig.ImagePullPolicy` to `corev1.PullIfNotPresent`, the fallback branch in `controllers/workspace/devworkspace_controller.go` that handles an empty project-clone image pull policy is unreachable.

Based on my understanding, the linked issue (#1674) specifically targets the project-clone container, but this post-merge fixup applies IfNotPresent to all init containers with an empty policy, including the restore container and any future init containers. Was this intentional broadening, or should this be scoped to just project-clone (and DWOC-defined init containers without an explicit policy)?
If the broader scope is intentional, it might be worth noting that in the PR description, and the RestoreConfig.ImagePullPolicy doc comment would need the same update as ProjectCloneConfig.

Yes, it was intentional for the default to apply to all init container to prevent workspace startup failures if for example the image registry is down. In my latest commit, I've updated the imagePullPolicy fields' documentation comments to mention this.
