chore: remove @angular/localize as peerDependency (#1604)

The ng-select package does not import any modules from @angular/localize.
Should a library user want to use @angular/localize in their project,
the Angular CLI will ensure they are using consistent @angular/* packages
along the way, thus it's not possible for the user to use a version that
is out of range.
