Use Vite instead of Snowpack

[itechify]

To align with evolving web development standards, we need to transition from using Snowpack to Vite for the build process in the extension-scaffold project. Specifically, this change should occur in the following directories:

es-home
es-runtime
es-common-extensions

Vite offers faster build times, improved hot module replacement (HMR), and better out-of-the-box compatibility with many popular libraries.

Here's a high-level plan to accomplish this transition:

• Install Vite: Add Vite as a devDependency in the package.json files of the above-mentioned directories.

• Configure Vite: Create and configure a vite.config.js file in each directory. The configuration should align with the current project structure and requirements of each directory.

• Update build scripts: Modify the build scripts in the package.json files to use Vite instead of Snowpack.

• Test the build: Run the build process and ensure that the application works as expected in each directory. This should involve manual testing as well as ensuring all automated tests pass.

• Remove Snowpack: Once everything is working with Vite, Snowpack can be removed from the package.json files. Also, remove any Snowpack-specific configuration files or settings.
