feat: Update Quickstart

[PuruVJ]

Description of Changes

Running the server wasn't working for me, lot of errors. This change does a few things:

• create-vite-app instead of create-react-app, speeds up npm install time and overall speed
• Get rid of testing-lib in the quickstart
• gitignore module_bindings
• Instead of separate client, server folders, server lives inside of the Vite App, which allows us to set up the spacetime:* scripts in a sensible manner

Changes to App.tsx

Avoided doing any changes to App.tsx as it reflects the quickstart guide, but some things were quite critical to change:

1. Move all query listeners to useEffect(fn, []). This is the most important, as before, the listeners were at the top level of the component. Which means, any state change(Even typing the message!) triggered the function to re-run, and by effect, recreate all the listeners without cleaning up the old ones, which caused quite a memory leak on even just changing the username.
2. Get rid of const client = useRef(spacetimeDBClient). Totally redundant.
3. Replace all let with const. Lets were giving off the impression that these values would be re-assigned later, but they never were.

TODO:

• Better styling of chat app
• Documentation for starting spacetime server, publishing to it, and connecting the UI to it
