Unable to use Yarn 2+

Issue Description

I'm trying to use yarn as my package manager, but ns build android fails with the following error: Command failed: yarn config get registry.

Seems like that config value doesn't exist anymore in Yarn 2+. It may have been renamed to the following:

❯ yarn config get npmRegistryServer
https://registry.yarnpkg.com

This seems to be the place where the command is ran:
https://github.com/NativeScript/nativescript-cli/blob/bb3a6965792cc565ab6d516c30a640ac98313ee7/lib/yarn-package-manager.ts#L127

Reproduction

Steps I've taken:

1. corepack enable
2. yarn set version berry
3. yarn install
4. Removed package-lock.json
5. ns package-manager set yarn
6. ns clean
7. ns build android

Relevant log output (if applicable)

Build output:
