Closes #10026

✅ Pull Request Checklist:

• Included link to corresponding React Spectrum GitHub Issue.
• Added/updated unit tests and storybook for this change (for new code or code which already has tests).
  • Not applicable: this is a starter wrapper prop-forwarding fix, and the starter does not appear to have existing tests for this component.
• Filled out test instructions.
• Updated documentation (if it already exists for this component).
  • Not applicable: this updates starter code only.
• Looked at the Accessibility Practices for this feature - Aria Practices

📝 Test Instructions:

Validated locally with:

• yarn install --immutable
• yarn eslint --no-warn-ignored starters/tailwind/src/Modal.tsx
• yarn lint

To verify manually, use the Tailwind starter Modal with overlay-control props such as isOpen, onOpenChange, and isDismissable. These props should remain on ModalOverlay and should not be forwarded to the inner React Aria Modal.
