Create an official Vite+TS template

[markerikson]

Should be basically identical to our CRA+TS template.

It should include Vitest and ESLint, so that you get testing and the rules of hooks stuff like you would with CRA.

A couple existing templates to use for reference:

• https://github.com/nvh95/vite-react-template-redux
• https://github.com/nickmccurdy/vite-react-testing

@nickmccurdy is up for doing the main work here
