Update template for React 18 and React-Redux v8

[markerikson]

We need to update this template to support React 18 and React-Redux v8.

This should include:

• Changing the template rendering setup to match React 18's createRoot(), per https://reactjs.org/blog/2022/03/08/react-18-upgrade-guide.html and Update templates to use React 18 createRoot facebook/create-react-app#12220
• Updating all dependencies to the latest
• Specifically updating react-redux to the latest 8.0-rc (and eventually 8.0 final, but I'd like to have the PR for the template ready before I release 8.0): https://github.com/reduxjs/react-redux/releases
