    docs: Split dependencies from related libraries
    
    We currently list everything as a dependencies, regardless of whether
    it actually is; this is a source of confusion for users that read the
    GTK documentation.
    
    Gi-docgen has a new "related" key in the project configuration which
    allows us to list libraries that are merely related to the namespace
    we are documenting; the "dependencies" key is used to document the
    actual namespace dependencies, now.
