fix(@angular/cli): update yarn berry package manager configuration

This commit updates the package manager descriptor for modern Yarn (Berry) to align with its current CLI options and configuration mechanisms:

- Removes `noLockfileFlag` as Yarn Berry does not support a direct `--no-lockfile` flag for adding packages.
- Updates `ignoreScriptsFlag` to use `--mode=skip-build`, which is the modern equivalent for skipping build scripts during installation.
- Changes `getRegistryOptions` to use `YARN_NPM_REGISTRY_SERVER` environment variable, which is the correct way to configure the registry in Yarn Berry.
