Yarn V2 compatibility

**Intended outcome:**

apollo commands should work normally when using Yarn V2 with Plug'n'Play

**Actual outcome:**

It fails with the following:

```

**How to reproduce the issue:**

Bootstrap any Yarn V2 project, add the apollo dependency and run any apollo command.

**Versions**

Tested with 2.21.2 and latest (2.25.0)

Start by bootstrapping a Yarn V2 project with Plug'n'Play, adding Apollo CLI 2.25.0, and running an Apollo command to reproduce the reported plugin and dependency-resolution errors. Trace the failing CLI dependency loading from the reported stack and verify that Apollo commands run normally in the Yarn V2 project without those errors.
