NodePackageLinkTask fails to execute in custom schematics

Description

I have created a custom ngAdd schematic, where I check a boolean option (--local), and if it is set I want to perform a link to a local package instead of the npm registry.

In order to do this, instead of:

context.addTask(new NodePackageInstallTask());

for each package I want to link I do

context.addTask(new NodePackageLinkTask(packageName));

However, the command fails. It seems that the actual command being ran is npm test-package where test-package is the package I want to link.

After checking the executor, it seems that the link command of NodePackageLinkTask is disregarded entirely: https://github.com/angular/angular-cli/blob/b4a12a9264033c18cdc2de81b05a2d1f41d549e2/packages/angular_devkit/schematics/tasks/package-manager/executor.ts#L91C9-L98

Minimal Reproduction

Follow the ngAdd tutorial, and use NodePackageLinkTask instead of NodePackageInstallTask`.

Exception or Error

Unknown command: `test-package`
