build: ensure material dependencies are properly linked for devtools (#60822)

This is a follow-up to the recent devtools linking change, leveraging
the dedicated package that we are also using in the components
repository; avoiding future duplication.

The latest version of that package contains a fix for an issue where
the linked bundles did not rewrite imports to shared chunks.

Such imports need to also point to their linked variants.
