The Python sigstore bundle use the new bundle format, the verification of which requires cosign>=4.2.0. Unfortunately alpine 3.21 is the earliest release with in this case version 4.2.1. The additional repository is necessary until 3.19 and 3.20 are dropped.
There is a draft PR to add sigstore validation to the "official" Python docker images which uses a similar approach. docker-library/python#983

Hm, I think the space variant also did not expand $PATH... I wonder how certain things even worked with that in mind 🤔
Anyways, this is the right thing to do 👍

PEP 761 deprecated the PGP signatures for CPython artifacts. Python 3.14 will only support verification with sigstore.
As all releases since
3.11.0include sigstore bundles, we can already update all docker files to use that instead.https://www.python.org/downloads/metadata/sigstore/
