Describe the enhancement or change
A clear and concise description of the request. What is the expected outcome?
`defaultProp have been removed in React 19. This issue is to track the work to remove this from our code base.

A quick search in re repo show code editor is still using this.
The work for this issue should also verify no use elsewhere.

Just a note: defaultProps is still valid for class components and should only be removed from functional components. See the "Removed: propTypes and defaultProps for functions" section from the React 19 upgrade guide
