[Bug]: Storybook code coverage should ignore storybook-static

[shilman]

Describe the bug

Storybok Test supports code coverage out of the box.

However, unless the user configures otherwise, it includes storybook-static in its coverage calculation. Since none of that code is tested, this makes the coverage results artificially low.

Since it's quite common to build a static storybook for any variety of reasons (including running the Visual test addon) we should exclude storybook-static from coverage out of the box if possible.
