Example: Drop "2" against "Qt Quick Controls" text

This should ensure that the examples give the same
message as the documentation. In addition,
dropped a phrase about Qt Quick Controls claiming
that it is designed for mobile and embedded. The
latest version of controls covers the entire spectrum.
