#### Testing the changes
- I tested the changes in this PR: **briefly**

The jupyter notebook seems to work ok (only pkg depending on this) although I'm not sure what action would really test it.

I tried to `./xbps-src check python3-jupyter_nbformat` but this is currently broken for a different reason.

I'm inclined to push this, in case someone finds a problem we'll at least know how to test in the future.
