Configure documentation links to allow localization

github.com and wikipedia.org have different localization behaviors depending on the URL.

If a language code is specified via the URL, then that language version of the page is loaded, regardless of the
language setting of the user's browser or GitHub. For example, this URL will take the user to the English version of the
page even if their browser is configured for Chinese:

https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/addressing-merge-conflicts/resolving-a-merge-conflict-on-github

If no language code is specified via the URL, then it redirects to the version of the page localized for the user's
language preference, where available. For example, if the user has selected "Chinese" as their preferred language in
their browser settings, then this URL:

https://docs.github.com/pull-requests/collaborating-with-pull-requests/addressing-merge-conflicts/resolving-a-merge-conflict-on-github

redirects to:

https://docs.github.com/cn/pull-requests/collaborating-with-pull-requests/addressing-merge-conflicts/resolving-a-merge-conflict-on-github
