[PATCH] deploy docs to qemu-project.org from GitLab CI

[Paolo Bonzini <pbonzini@redhat.com>]

Currently, the website is rebuilt on qemu-project.org using
a separate container (https://github.com/stefanha/qemu-docs/)
cron job hook.  We can instead reuse the GitLab's CI artifacts.

To do so, we use the same mechanism that is already in place for
qemu-web.git.
