[CL-524] Ignore flaky elements in Chromatic tests

[vleague2]

CL-524

📔 Objective

We're seeing some frequent and noisy Chromatic diffs for stories that have no changes.

For the kitchen sink stories, it is usually the menu component being positioned ~1px lower or higher than the previous build, or the virtual scroll story showing more or less rows of data in the screenshot. These are not actual useful diffs, so this PR is going to try to ignore the elements that are causing the diffs while keeping the stories around.

For the popup layout stories, we are still working on debugging why sometimes the snapshots include all the item info, and sometimes they don't. The Storybook live instance consistently shows all the item info as expected, so it is an issue with how the snapshots are getting taken. While we work to figure this out, we are disabling the tests entirely so that developers are not constantly seeing diffs to these stories.
