fix(ci): correct variable name for deployment comment check in PR-Demo-cleanup workflow (#3946)

# Description of Changes

- **What was changed**  
- In `.github/workflows/PR-Demo-cleanup.yml`, updated the GitHub Script
step to properly destructure the list of comments and renamed the flag
from the undefined `deploymentComment` to `hasDeploymentComment`.
- Enhanced output logic to set the `present` flag based on either label
presence or comment presence.

- **Why the change was made**  
- The cleanup job was failing with a `ReferenceError: deploymentComment
is not defined` because the variable used in `core.setOutput()` did not
exist.
- Ensuring the flag accurately reflects whether a deployment label or
comment was present prevents unexpected workflow failures.
