Use the Material UI "required" prop

[stevenmckinnon]

Is your feature request related to a problem? Please describe.
When marking a field as required, it only adds the asterisk to the label text rather than using the required prop in InputLabel, which doesn't add the separate <span /> Material UI renders. Therefore the styling can't be overridden (i.e. style it as red by default).

Describe the solution you'd like
Use InputLabels's required prop

Describe for which setup you like to have the improvement
Framework: React
RendererSet: material

Additional context

Good idea!

It's not really a duplicate. The other issue specifically mentions optional required properties based on if/then/else which is much harder than a general support of Material Ui's required prop. Actually these issues are orthogonal.
