React support for "defaultProps" is being removed.

Saw a warning recently in a downstream app that:

Support for defaultProps will be removed from function components in a future major release. Use JavaScript default parameters instead.

Example: https://github.com/CareEvolution/MyDataHelpsUI/blob/main/src/components/presentational/ProgressBar/ProgressBar.tsx#L22-L26

We should probably go through our existing components and convert any usage of defaultProps ahead of that change.
