Angular: update addon interactions example

[yannbf]

Issue: N/A

What I did

Added a form example in examples/angular-cli so we can do more complex interactions:

How to test

• Is this testable with Jest or Chromatic screenshots?
• Does this need a new example in the kitchen sink apps?
• Does this need an update to the documentation?

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

Edit: Nevermind, the problem was not my code, it was actually the argTypeEnhancers from addon-docs! Will create a github issue for those

For some reason the code was working great and stopped working even though I changed it back to the state that was working perfectly. I think there's a cache issue going on in SB for angular. Whenever I made changes in the angular component, the values were not updated in Storybook and I had to restart it 🤔

@ThibaudAV could you please help out fix the following issue? Might be easy peasy but I can't figure out why that is happening 😭
