Fix detection of node_modules/ in monorepos

We need a way to find node_modules for monorepo that is more robust
This is especially sticky for monorepo projects where something like `@openzeppelin/*` is not installed in the relative `node_modules/` but in the root workspace. Yarn 2 removed nohoist as well, so I haven't really found a good solution to this yet.

A temporary workaround is to symlink the relevant packages into the relative/workspace's `node_modules/` dir but that gets pretty annoying and is temporary.

ETA: A solution is adding the following to the `package.json` for the contract package:

"installConfig": {
"hoistingLimits": "dependencies"
},
