[e2e-test-cleanup] Clean up e2e-storybook test for <c4d-content-item>

[m4olivei]

Description

This task is to update the e2e-storybook tests for the <c4d-content-item> component to match the v2 specifications. Relevant links:

v2 Figma specifications
e2e-storybook test source code

At the completion of this task, there should be no tests in this components *.e2e.js file marked as skipped. The goal is that the existing tests are updated to be relevant for v2 specifications. In some cases, that might mean simple updates to match the markup structure, naming and style changes in v2. In other cases, tests may be irrelevant given the context of v2. There is some discretion involved. Where possible, document decisions made. Also take note of when and where Percy screenshot testing is covering components. If Percy tests are present for a given component and configuration, there may not be a need for further integration testing.
