    build: Improve GtkDoc documentation generation
    
    The `gtkdoc` method also supports a parameter called
    `ignore_headers` so there is no need to use a custom `scan_args`
    flag.
    
    `version.xml` file has also been added as a content file for
    correctness.
    
    Finally, the `gobject_typesfile` parameter has been removed becuase
    `--rebuild-types` parameter is already provided.
