Update react-scripts, eslint, typescript, rollup deps

[rpoet-ds]

https://dotsub.atlassian.net/browse/VTMS-3439

The large number of file changes is because of a change in importing React, it is no longer needed and typescript flags it as an error:

microsoft/TypeScript#41882
https://reactjs.org/blog/2020/09/22/introducing-the-new-jsx-transform.html

I ran npx react-codemod update-react-imports to update the react imports.
