bug: "Can't find stylesheet to import" when using Yarn PnP

[x] Bug Report
[ ] Feature Request

Description

When migrating our library to use Yarn PnP, it's no longer resolving the @angular/material sass api at build time. This resolved fine prior to the pnp shift. @angular/material is declared as a peer dependency of the library (and installed as devDep for testing)

× Compiling with Angular sources in Ivy partial compilation mode.
Can't find stylesheet to import.
  ╷
6 │ @use '@angular/material' as mat;
  │ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  ╵

How To Reproduce

In a library project within a repo using yarn pnp, try using the root sass api from @angular/material within a component's stylesheet.

@use '@angular/material' as mat;

When building, it should fail to resolve.

Expected Behaviour

Should build successfully
