What is the new behavior?

Fixed the gap between ion-toggle and kirby-toggle, that occurred since the ion-toggle behaved as an inline element. The new behavior is making kirby-toggle display inline-flex, which eliminates the gap without changing the outwards behaviour of kirby toggle.

Nice work 😎

I think you should change the PR title before merging. "Add display inline-flex on kirby toggle" is a bit too implementation specific. It should say something about which bug the PR fixes. Keep in mind, that it ends up in the changelog.
