docs: Convert Badges sysadmin SOP into Badges docs page
    
    This commit moves the Fedora Infra Docs SOP originally written in
    ReStructuredText into an AsciiDoc file in the Badges docs site:
    
        https://docs.pagure.org/infra-docs/sysadmin-guide/sops/badges.html
    
    Once this is merged into fedora-badges.git, I will follow up with a PR
    to the infra-docs.git repository to point to the new home of the SOP so
    there are not multiple sources of truth published at the same time.
    
    Also I tested all of the internal links and validated that they work.
