Unable to sync spaces when new root is created

### Brief bug description

When syncing a space that links a new web spotlight root, the operation fails since there is no matching item in the target environment.

### Repro steps

1. Create a new space that links a new root.
2. Sync spaces
3. See an error like the following `"The referenced root item '{codename: root}' was not found. Provide a reference to an existing root item."`

### Expected behavior

Preferably I'd like to see the root item synced. However, I understand that this may not be in line with the expectations of the `sync` command.

### Test environment

- `data-ops@2.2.2`

### Additional context

If we were to create an item if there's a new root, it would need to happen after content type updates, but before spaces. This is an issue since these operations are in the opposite order in the current implementation.

### Screenshots

N/A

Start with the spaces sync command and trace the ordering of content type updates, root item handling, and spaces. Reproduce the failure with a space linking a new root, then determine the supported completion behavior: syncing the root without the missing-reference error or clearly documenting that the sync command does not create it.
