Rich-Select: Add an example or reference to model-value-changed

[lpoulter]

I was confused for a while how to listen for a value change. I tried the native @change but that didn't work. I found out I need to use @model-value-changed by searching the slack archives. Related why does listener for a change event not work?

The recommended usage is to use @model-value-changed everywhere: it's a normalized, single source of truth event for all FormControls. The reason change works for other elements is because they have a native input/select/textarea underneath that fires the event.

If you have tips about how we can improve docs, let us know ;) I'm still hoping we have time to write a set of best practices and tutorials for forms one day.
