We have some links on the site using https://hibernate.org/foo and not foo/
These get downgraded to http by GitHub infra.
Let's make sure all our links are of the form https://hibernate.org/foo/

For now enforcing HTTPS in GitHub sorta workaround it but better be clean. It is also better because it avoid an unnecessary redirect.

Example of such links menu links to roadmap, menu links to documentation
