peerDependency warning on build (Affects dev only)

[Gaurav0]

There is a peerDependency warning while installing this package.

Missing peerDependency webpack@^5.0.0 required by ember-source, ember-auto-import, etc.

As these are not dependencies, this does not affect users of this package.

The easiest way to fix is to add some version of webpack 5.x to devDependencies.

I can open a PR if you'd like.
