Yarn Berry (v2 & v3) is not supported: Unsupported option name ("--no-lockfile")

Hi!

When trying to run `yarn test:ember-compatibility` in my addon, I receive:

```
❯ yarn test:ember-compatibility
Unknown Syntax Error: Unsupported option name ("--no-lockfile").

$ yarn install [--json] [--immutable] [--immutable-cache] [--check-cache] [--inline-builds] [--mode #0]
Error!
1
undefined
```

This is because Yarn Berry does not have the `--no-lockfile` option.

I cannot use Yarn 1 because it crashes on `nohoist: *`, and package hoisting in my monorepo breaks many things.
