Use shared layout for worldwide_corporate_information_about_page views

⚠️ This repo is Continuously Deployed: make sure you follow the guidance ⚠️

What/ Why

• Use the shared layout for worldwide_corporate_information_about_page such as https://www.gov.uk/world/organisations/british-embassy-dakar/about/recruitment and https://www.gov.uk/world/organisations/british-embassy-dakar/about/complaints-procedure
• PR links: https://govuk-frontend-app-pr-5749.herokuapp.com/world/organisations/british-embassy-dakar/about/recruitment and https://govuk-frontend-app-pr-5749.herokuapp.com/world/organisations/british-embassy-dakar/about/complaints-procedure
• I've moved the Contents List above the content. Without this, the page looked a bit weird as the Contents and Header would be left aligned, but the content would be further to the right. Therefore stacking it looked a bit nicer in this instance.
• Jira card: https://gov-uk.atlassian.net/browse/PNP-10129

Non-blocking: I note that this page already used the article tag. I think this is the first time I've noticed it in a page during this piece of work, so we should maybe have a broader conversation about the use of article in page types, as if it's appropriate we should use it everywhere to be consistent.

@andysellick Should be ready for another review 👍

Looks good. I think this is the last use of some of the worldwide partials - want to pair on cleaning them up?

Thanks @andysellick, sounds good 👍
