[RadioButtonGroupInput] Hope Support disable some option

[scq000]

When I use RadioButtonGroupInput component, I wish I can disable some choices by providing a disableValue field which name is disabled.

Example:

 const choices = [
     { id: 123, name: '12' },
     { id: 456, name: '18' },
     { id: 976, name: '30', disabled: true },
  ];
<RadioButtonGroupInput source="age" choices={choices} />

Hi @scq000,

Nice idea! The core team developers won't implement that feature in the near future because they don't need the it for their own projects. But feel free to open a PR, targeting the next branch. In the meantime, you can still replace RadioButtonGroupInput by your own component.
