Use govuk publishing components content list to prevent hyphens being read out by screenreaders

[beccapearce]

What

Use the contents-list from govuk-publishing-component to render the list of corporate information pages for worldwide organisations.

Why

The contents list component has a fix for an issue where nearly every screen reader reads out the hyphen as either “dash“ or “hyphen“ before each item/link in the Corporate information list. Screen reader users found that frustrating to read through, so this should improve the experience.

Closing this PR in favour of another one that uses the list component to solve the same issue. By using the list instead of the content-list we avoid adding a confusing contents heading to the list
