    Dockerfile: refactor to avoid fedora:33 stage
    
    We've been using an intermediate `fedora:33` stage to build DevDocs,
    because of our dependency on `ruby-2.7.6`. The consequence of this is
    that we've not been generating documentation with the current version
    of `g-ir-doc-tool`, which is becoming more of a problem now.
    
    Some notable quirks:
    
    * After installing the builddeps for ruby, we have to force install
      `openssl1.1-devel` for it to build correctly
    * Because `gobject-introspection-1.74.0` is incompatible with
      `python3-markdown-3.4.1`, we install `Markdown-3.3.7` using `pip3`
