Yarn workspace dependencies

[xjunior]

Yarn workspaces expect dependency versions to match the specified in package.json. When they don't match, the dependencies fall onto the unmatchedWorkspaceDependency sections. This PR aims to work closer to the yarn workspaces specification. When the version matches, yarn workspaces is responsible for linking them automatically.

This PR also refactors the workspace implementation in a way that avoids prematurely reading all workspace package.yml files.
