Storybook: Add colour picker in addon-backgrounds

[leoyli]

Is your feature request related to a problem? Please describe.
If work in CDD approach, sometimes we may want to quickly change the iframe background colour. It is tedious to add colour definition in to a story just to see the colour each time...

Describe the solution you'd like
Add a colour picker or at least a field that accept colour name.

Describe alternatives you've considered
N/A

Are you able to assist bring the feature to reality?
Add a field to accept colour dynamically, yes; add a colour picker, it requires some changes in the UI side I believe.

Additional context
The old predefined colour set is still very useful and we probably don't want to change it; my proposal is just to augment the add-on so it can be more robust.
