[cli][tests] Work around Yarn + Corepack issue in tests (#10858)

CI started failing on corepack related tests with error:

```
error This project's package.json defines "packageManager": "yarn@npm@8.1.0". However the current global version of Yarn is 1.22.21.
```

This appears to be a bug in the Yarn v1.22.21, which was released a week ago: https://github.com/yarnpkg/yarn/releases/tag/v1.22.21

Setting the `SKIP_YARN_COREPACK_CHECK` env var disables this new check which fixes the issue for us.

**NOTE:** Review with [whitespace changes disabled](https://github.com/vercel/vercel/pull/10858/files?w=1) for an easier view.
