Delete all unused "import React from react" statements

[PaulRBerg]

Starting with React v17, JSX can be used without importing React. No longer do we have to import React in the global scope, or add it as a dependency:

There's an eslint plugin preventing this in the current version. It either has to be removed or the rule itself suppressed.

Nevermind, Docusaurus is not compatible with the new JSX transformer:

ReferenceError: React is not defined.
