Add Vite React Example

[KevinRobben]

Eel react app starter template with Vite based on #95. The ReadMe file has instructions on how to start the project with a virtual environment and deploy it with pyinstaller.

The template has the following features (from readme):

• Multiple instances To enable multiple instances of this application in production (i.e. the user opens the application multiple times), a new free socket port is searched for on app startup and injected in to ./dist_vite/index.html and ./dist_vite/assets/index.*.js before eel.init().
• Splashscreen A default splash-screen is provided so the user had direct feedback when the .exe file opened

@KevinRobben great work! I downloaded your example and followed the instructions in your README.md . Works well on my OS: Ubuntu 22.04.2 LTS x86_64, including bundling with PyInstaller. I'm not a maintainer, but I would love to see this PR merged into main.

Love this. I pulled it down to test it and it ran really well.
