Build Execution Environment instructions fail due to changes in the latest fedora image

[2q2code]

Following instructions here:
https://docs.ansible.com/ansible/devel/getting_started_ee/build_execution_environment.html

Leads to:

# ansible-builder build --tag postgresql_ee --container-runtime docker
Running command:
  docker build -f context/Dockerfile -t postgresql_ee context

The command '/bin/sh -c /output/scripts/pip_install $PYCMD' returned a non-zero code: 1

An error occurred (rc=1), see output line(s) above for details.

It took me a day of messing around with this to figure out that the base image was at fault, and not my approach. I tried using pipx-installed ansible tools, and a venv using pip3. Neither worked, but they had the previous day on another machine running the same OS (arch).

Might want to lock this down to a base image version that works and not a moving target for the poor newcomer with less determination to make it work.

Thanks for your Ansible docs contribution! We talk about Ansible documentation on Matrix at #docs:ansible.im if you ever want to join us and chat about the docs! We meet on Matrix every Tuesday. See the Ansible calendar for meeting details. We welcome additions to our weekly agenda items too. You can add the dawgs-meeting tag to a forum topic to bring it up at the next meeting.

@Andersson007 - can you take a look when you get a chance pls?

And thanks @2q2code for opening the issue!

@2q2code hi, thanks for reporting the issue!
Would you like to contribute and change the doc yourself with a fedora image version that works?
There's the Edit on GitHub button on the page

Oh. I might do that but I ended up using a ubi9 image. It isn't much better because it still uses the 'latest' tag, which leaves it open to fail in future. I will have a look later today.
