Is your feature request related to a problem? Please describe.

The deprecated keyword is a boolean that indicates that the instance value the keyword applies to should not be used and may be removed in the future. It has been added in version 2019-09.

Describe the solution you'd like

It would be nice if behaviour of deprecated keywords could be influenced by the RJSF options (e.g., hiding them, disabling them, displaying them in gray, or whatever).

Describe alternatives you've considered

@GlassOfWhiskey Is this something you are open to implementing? I'd lean toward adding a global prop in the UiSchema that controls whether they are hidden, disabled, or noted as deprecated in the UI's label (default behavior). At minimum, updating the labels to add (deprecated) on them would be a good starting point.
