Suggestion: remove all 'boolean' examples from storybook

The storybook includes 'boolean' error examples. Example:

I think all such examples should be removed. They are not part of the design system and should never be used. We would never want to present errors without error messages.

If theres's some reason they exist that I'm not aware, of I would suggest adding annotation to note they are not for regular use.
