fix(feedback): Clarify the difference between createWidget and create Form in the feedback public api (#11838)

Prior to this PR it was only possible to get the floating feedback
button if you configured `autoInject: true`.

In our uses on sentry.io we want to be able to show that button on some
pages, but not others. This make it possible, the (react hooks) code to
do that is:
```
useEffect(() => {
  const widget = feedback.createWidget(options);
  return async () => {
    widget.removeFromDom();
  };
}, []);
```
