Resolve #3477138 "Implement comparison cards"

Closes #3477138

Testing steps

• checkout the drupalorg project to https://gitlab.com/drupal-infrastructure/sites/drupalorg/-/merge_requests/49, clear caches and import config

• for up to date mother node test content checkout the drupalorg contrib issue to this fork https://www.drupal.org/project/drupalorg/issues/3477134

• Note: if you run composer recreate it will default you to a different version of the default content, so if you need to run that, checkout to this branch after you run it, and then re-import the default content. (see docs in the drupal org module if needed) Once you are spun up:

• run composer install-storybook; ddev yarn storybook`

• Visit storybook and verify these components are rendering correctly:

• Visit the mothernode

  1. Verify that the feature list still looks good.
  2. Verify the comparison cards look good. The spacing is not identical to the design. That was an intentional choice for uniformity.

• Edit both the feature and comparison card Card lists and test the background and text alignment settings.
