[YOU54F]

https://pact-foundation.github.io/pact-python/API/

and

https://pact-foundation.github.io/pact-python/api/

don't route to the same page, unsure if it should, so update link

Pull Request Overview

This PR fixes a case sensitivity issue in the API documentation link. The URL was pointing to /API/ (uppercase) when it should point to /api/ (lowercase), as these resolve to different pages.

Thanks for catching that! I didn't realise it was case sensitive, and I think I changed the convention early one to default to kebab-case for the URLs
