CmdPal: Fix desynced resmanager files (#42038)

## Summary of the Pull Request

This PR fixes desynced resource manager files introduced by previous
commits.
While Visual Studio would regenerate and correct these files
automatically, applying this fix preemptively reduces unnecessary churn
in unrelated commits and avoids redundant file changes.
