maint/extract-md-links doesn't work with python3-mistune 3.0.2-2

I'm unable to run maint/extract-md-links on arch (it looks like the script is only known to work with python3-mistune 2.0.4-1?):

Traceback (most recent call last):
  File "/home/gabi/code/other-arti/maint/extract-md-links", line 117, in <module>
    print(extract_links(text).as_json())
          ^^^^^^^^^^^^^^^^^^^

    renderer = renderer=mistune.AstRenderer();
                        ^^^^^^^^^^^^^^^^^^^
AttributeError: module 'mistune' has no attribute 'AstRenderer'. Did you mean: 'BaseRenderer'?
