Avoid GH board automation permissions error (#1691)

## Motivation for the change, related issues

The GitHub board automation workflow is failing due to a permissions
error when attempting to create a label for the wporg-theme-directory
repo.


https://github.com/WordPress/wordpress-playground/actions/runs/10459089537/job/28962281299#step:3:7002

```
      ["message"]=>
      string(71) "adamziel does not have the correct permissions to execute `CreateLabel`"
    }
  }
}
Error processing card: WordPress/wporg-theme-directory#14 (WordPress Playground Integration Planning)
GraphQL query failed
Skipping that one and continuing...
```

## Implementation details

This change simply skips label updates for the wporg-theme-directory
repo for which we do not have permission to create new labels.

## Testing Instructions (or ideally a Blueprint)

- Test by manually running the board automation workflow from this PR's
branch and make sure the workflow succeeds.
- Try changing another issue's board status, rerun the workflow, and
observe that the status is reflected in changed issue labels.
- Restore the original issue status, rerun the workflow, and observe the
original label has been restored.
