add forwardRef support to addon-info

[yjcxy12]

Issue: closes #4787

What I did

• added react-is to dependencies in addon-info.
• in both Node and Story checks if the element is forwardRef element and parses accordingly.
• add new example of forwardRef component in kitchen sink app.

How to test

• Is this testable with Jest or Chromatic screenshots?
  Yes.
• Does this need a new example in the kitchen sink apps?
  Yes.
• Does this need an update to the documentation?
  Don't think so.

If your answer is yes to any of these, please make sure to include it in your PR.

In docs they mentioned to just use a dislpayName.
Is your solution better ?

@yjcxy12 this is awesome! thank you!

This code throws when the component uses a react hook.

See this issue: #6848

I've been able to make some adjustments to make that use-case work, I'll open a PR momentarily. Will you be able to review @yjcxy12

Perhaps a solution based on displayName would be better indeed @igor-dv
