brace yourself, this code needs cleanup.. if it works that is..

Ok.. so I think I got this into the shape it can be in and, it doesn't work.

• I seems my changes trying to fix pnp breaks vite, for some reason.
• But worse of all, my changes seem to not even fix pnp. Or at the very least I can't get the sandbox to work.

I was able to find where files supposedly are according to pnp by asking the pnp api:
require(pnpFile).resolveRequest('@storybook/addon-docs', './')

This actually yields a place in the fs!
Unfortunately node can't use it, because (I assume) it's in a .zip file.

So I'm afraid this isn't a viable method of suppurting pnp.
