I updated the devDependencies in both starters/minimal/package.json and starters/standard/package.json to the following versions, which were reported to cause failures:
The smoke tests for both starters failed with the exact error reported by users: Error: Build failed with 1 error: error: Must use "outdir" when there are multiple input files. This confirms that our smoke test suite is effective at catching this type of regression.
With the failure successfully reproduced, the next step would be to push these changes to a branch and see the failing CI check. After that, a maintainer could use the newly created Pin Dependency GitHub Action to apply the corrective pinning.
