/**
* Yarn Plug'n'Play means that dependency hoisting doesn't work like it normally
* would with the standard `node_modules` configuration. This is by design, as
* hoisting is unpredictable.
*
* This plugin works around this by ensuring references to `@babel/runtime` (which
* is required at build-time from an extension/core's scope) are redirected to the
* copy of `@babel/runtime` which is a dependency of this package.
*
* This removes the need for hoisting, and allows for Plyug'n'Play compatibility.
*
* Thanks goes to Yarn's lead maintainer @arcanis for helping me get to this
* solution.
