fix(rust): Add missing commas in python IR interchange

[wence-]

Easy issue with "untyped" code, sorry! (cc @MarcoGorelli)

I also added myself as codeowner for the python IR subsystem: so that I get a heads up when things are changing (cc @ritchie46)

Yes, that's a good one!

I suspect you'll need to add me with write access to the repo as well.

@wence- I think the title of the pull request is wrong, it should be python, not rust.
