QOptionGroup no example demonstrating usage of feature option-value and option-label

[jose-rocha]

Context

As i was browsing the release notes, i came across the feature of new props for option-value and option-label.
i was interested but couldn't really understand the purpose. It was only as i was once again browsing the release notes and came across issue #17710 and saw the example given by the OP, that i finally got what those props were used for.

I think it would be good to include some example of those props being used in the Options Group Page, so that anyone interested in using the component don't miss it by accident.
