Only support webpack 5, expose some types

[IanVS]

Issue: #

What Changed

We lost #28 in #30, so this re-exports a few types that are useful when interacting with this package. It will be useful to avoid duplicating the types here: https://github.com/storybookjs/storybook/pull/20271/files#diff-e3d50a086df937d7c8f41d5819f0e6d8368961c112866cc291cfe057a4fafe23R10

It also removes some logic that was supporting webpack 4.
