imports autocomplete does not work with pnpm

[Peersky]

OS: Mac OS

Steps to reproduce:

1. Take project that is able to autocomplete imports for yarn
2. Remove yarn.lock and node_modules
3. run pnpm install
4. Attempt to import something from installed packages in to solidity file.

In my case import paths resolve and compilcation is successful, however autocomplete won't work and I am getting VSCode errorr:

Invalid import: wrong file casing hardhat(409)
