Medusa store doesn't work for pnpm without hoisting

[RickVM]

Bug report

Describe the bug

We have a preference for pnpm due to its improved performance. Installing packages with pnpm however does not work, unless if you create a .npmc with node-linker=hoisted

I'm not sure where this issue originates from, but having to resort to hoisting with pnpm gives a flat node modules like yarn, and removes the the improved performance

System information

Medusa version (including plugins): Medusa CLI version: 1.3.19 Node.js version: v18.16.0 Operating system: MacOS Ventura 13.4.1 (c) - ARM M1

Steps to reproduce the behavior

1. Create app with medusa new (yarn is used to install the packages, would have preferred being able to use pnpm here as well but thats something for another issue/feature).
2. remove node_modules and lockfile
3. pnpm install
4. pnpm run dev (or medusa dev)

Then you get a whole list of errors of missing dependencies:

Expected behavior

App starts like normal with all dependencies

A clear and concise description of what you expected to happen

Additional context

Hoisting is fine for now but might have some time to work on this issue at a later time. Would be eager to hear what's already known on this

I think the problem lies in how Yarn was configured: https://github.com/medusajs/medusa/blob/b5bc33a9d7b94886189819b34b7d934e27a0d196/.yarnrc.yml#L7

To fix this issue, it's necessary to remove that line, but doing so can potentially cause a lot of other issues as well.

Moving to a pnpm workspace is another option, but it will require a significant amount of effort.
