Use nodeLinker: pnpm for Yarn installations

[jonkoops]

This issue is a follow-up of #9959. In order to make the installation of packages more performant nodeLinker: pnpm should be configured for Yarn. This links the local node modules from a central content addressable store using symbolic links, avoiding an expensive copy operation. This has the added benefit of catching silly bugs such as phantom dependencies, which might lead to unexpected behaviour.

@tlabaj I think this is something worth getting in post v6. I don't think it would be much risk to add it during what we are doing now but with the release looming I wouldn't want to introduce right now. @jonkoops Let me know what you think.

Yes, this a development enhancement that can wait until after v6.
