fix(tabs): server-side rendering error when aligning ink bar (#5455)

* Fixes a server-side rendering error in the ink bar due to a lack of `requestAnimationFrame`. The error is being logged, but it didn't fail the build, because it happens in a lifecycle hook.
* Enables the checkbox and button toggle cases in the kitchen sink since it looks like they're not failing anymore.
