Docker Socket API broken after Python update

Describe the bug

Since the latest update to some Python packages it is not possible anymore to access the Docker API via unix://var/run/docker.sock. All connection attempts fail with Not supported URL scheme http+docker universally on all Photon OS servers. This entirely breaks monitoring with all Python based monitoring solutions (like Check_MK) and likely much more.

The bug is in one of those packages:

python3-jinja2-3.1.2-5.ph5.noarch
python3-requests-2.28.1-6.ph5.noarch
python3-xml-3.11.9-7.ph5.x86_64
python3-libs-3.11.9-7.ph5.x86_64
python3-3.11.9-7.ph5.x86_64
expat-2.6.0-6.ph5.x86_64
expat-libs-2.6.0-6.ph5.x86_64

Reproduction steps

1. run Photon OS with all updates installed
2. enable and start Docker
3. install package python3-pip
4. run pip install docker==7.0.0 (with latest version 7.1.0 the library is broken as well)
5. run this script: https://gist.github.com/felixlabrot/c96a6d2018b7ee7dcb004a032f5c323a

Expected behavior

It should be possible to connect to the Docker API like it was before.

Additional context

No response

Reproduce the failure on an updated Photon OS server by following the listed Docker and pip installation steps, then run the linked reproduction script. Compare the listed Python package versions and Docker library versions to identify the compatibility break. Done means the script can again connect through unix://var/run/docker.sock without the http+docker scheme error.
