There's a merged pull request on the void-packages repository

python3-feedparser: update to 6.0.1.
https://github.com/void-linux/void-packages/pull/25541

Description:
- Split off from python-feedparser.  Python2 version is now deprecated and unsupported by upstream:

    https://github.com/kurtmckee/feedparser/issues/228

  Since no other packages in void-packages now depend on python-feedparser, drop Python2 version.

- python3-feedparser now requires separate python3-sgmllib (which was provided in Python2 and bundled in Python3 module previously).
