Update from Webpack 4 to Vite

[nataliepina]

Description

We'd like to update from Webpack 4 to Vite. This will lead to faster build times.

The new version of Storybook (7) is in beta testing and set to release soon. With this new version, Vite or Webpack 5 will be suggested. Upgrading our builder will allow for build optimizations, such as lazy compilation and filesystem caching.

There may be some caveats to this update alongside Storybook and some research to be done there to resolve any issue while updating.

Acceptance Criteria

Migrate from Webpack 4 to Vite.
