fix(angular): ensure crystal targets for testing when bundler=rspack (#30631)

## Current Behavior
Angular Rspack relies on Inferred Targets however, when scaffolding the
application, the unit test runners are being set up with executors.

## Expected Behavior
Ensure that when `bundler=rspack` unit test runners are being set up
with inference plugins
