    doc: drop release notes + fix sphinxmark

    The ops repo isn't really software. It's a collection of playbooks
    that we share between operators, therefore, release notes are a bit
    confusing because there are so many playbooks inside of it.

    They're also broken because of how we have a few links all over the
    place. There has been no release notes published either.

    sphinxmark is no longer compatible with the latest release of Sphinx
    which is causing all of our documentation jobs to fail. This patch
    removes it as our current usage of openstacktheme for documentation
    already provides watermarks for current branch and notices for which
    branch the documentation covers.
