All links in the documentation page are broken

All links in https://aurora.apache.org/documentation/latest/ are returning 404.

The documentation page is linked in the home and it gives a really bad experience to all new users that are looking for the documentation.

The problem is that they added the extension by mistake e.g. it points to https://aurora.apache.org/documentation/latest/features/containers.md if you remove the `.md` from the link it works fine.
