feat: Use Vite in the template

[baptistegrimaud]

Description

Update template as per #63:

• convert the sample components to Typescript (and configure a tsconfig.json)
• setup Prettier and ESLint (and configure VSCode/IntelliJ auto-save)
• bundle with Vite instead of Webpack
• add a note in the README.md for Windows users to install PowerShell
• add a sample Github workflow to build the project

The only remaining part is to create a sample hello world, but we need first to define the exact scope of what should be showcased.

Additionally, the test create-templatesSet-project.test.js has been rewritten from Jest to node:test.
