Add 2xl and xl storybook dark snapshots

Related to #4305 by @zackkrida

Description

This PR adds the storybook dark snapshots for tests that use breakpoints for 2xl and xl breakpoints. They were not updated in the previous PRs that added the Playwright snapshots because the new snapshots do not fail the CI (#4927)

Testing Instructions

The CI should pass, and there should only be new dark snapshots in this PR.
