fix: incorrect import causes storybook build to fail

[delanni]

Summary

This change in this PR: #167998 is causing an error in building storybooks: https://buildkite.com/elastic/kibana-on-merge/builds/38046#018bb9d2-7820-43ad-9144-e40d33d28c3b

In brief, the import looks like this:

import { css } from '@emotion/react/dist/emotion-react.cjs';

but it should be like this:

import { css } from '@emotion/react';

It looks it's a bad import, we should set up a pre-merge check for these accidental auto-imports.
