ns clean - should remove yarn.lock if the package manager for the project is yarn

Is your feature request related to a problem? Please describe.

When you run ns clean on a project that uses yarn as the package manager, the CLI still tries to remove a package-lock.json instead of yarn.lock

Describe the solution you'd like

If the package manager of the project is yarn, then ns clean should attempt to remove yarn.lock if it exists.

Describe alternatives you've considered

As an alternative, the developer could be prompted if they wish to remove yarn.lock or package-lock.json.

Anything else?

Start by tracing the ns clean command and how it determines the project's package manager. Verify the cleanup behavior for Yarn projects and confirm completion by ensuring yarn.lock is targeted when present instead of package-lock.json; add or run the relevant cleanup tests if they are found.
