[InputBase] Use ref prop instead of inputRef prop on input component

[GuilleDF]

Breaking changes

• [TextField] Change ref forwarding expections on custom inputComponent.
  The component should forward the ref prop instead of the inputRef prop.

  -function NumberFormatCustom(props) {
  -  const { inputRef, onChange, ...other } = props;
  +const NumberFormatCustom = React.forwardRef(function NumberFormatCustom(
  +  props,
  +  ref,
  +) {
    const { onChange, ...other } = props;
  
    return (
      <NumberFormat
        {...other}
  -     getInputRef={inputRef}
  +     getInputRef={ref}

---

The input component was passed an inputRef prop in order to use refs with custom components. Thanks to React.forwardRef, we can change this to simply use the normal ref prop.

This resolves #22253

Hmm, not sure why the CI is failing... Any ideas? 😅

@GuilleDF A flaky test. It's a great first pull request on Material-UI 👌🏻. Thank you for working on it!
