RangeControl: Missing disabled style and behaviour.

[pento]

Describe the bug

After the changes in #19916, setting the disabled prop on a RangeControl component no longer makes it appear disabled.

Additionally, the disabled prop is not being passed to the InputNumber, so the value of the RangeControl can still be changed, despite being disabled.

I also noticed that the disabled prop isn't shown in the RangeControl storybook.

To reproduce

Steps to reproduce the behaviour:

1. Create an instance of RangeControl, with the disabled prop set to true.
2. Observe that the styling of the slider appears the same.
3. Change the value in the number input, see that the slider changes.

Expected behavior

That the value of the RangeControl doesn't change when it's disabled, and it has a visual appearance of being disabled.
