ng g @angular/core:standalone does not migrate spec files #48944
Description
Which @angular/* package(s) are the source of the bug?
core
Is this a regression?
No
Description
ng new standalone-migration --defaults
cd standalone-migration
ng update @angular/core@next @angular/cli@next --force
ng g c hello
ng g @angular/core:standalone --defaults --mode standalone-bootstrap
neither app.component.spec.ts nor hello.component.spec.ts is migrated, so ng test fails.

Unexpected "AppComponent" found in the "declarations" array of the "TestBed.configureTestingModule" call, "AppComponent" is marked as standalone and can't be declared in any NgModule - did you intend to import it instead (by adding it to the "imports" array)?
