By switching to block style (`|`) with clip (no `-` or `+`) the failure
messages don't require quoting and gain a single trailing newline. This causes
Ansible to print them as block style, when using the yaml stdout callback
plugin. As a result the values have one less layer of quoting and quote
escaping, making them much easier to read.
Relying on the virtualenv default or hardcoding "python" results in a Python
2.x virtualenv on some targets (e.g. debian10-test). This caused a failure
when testing with Ansible >= 10 (ansible-core >= 2.17), which have dropped
Python 2.x support.

../data/stubs/stub-kubectl.py exec -it localhost -- /usr/bin/python -c "...":
Traceback (most recent call last):

It's not clear why this is happening. "stub-kubectl.py" is executed with
the 2.7 virtualenv, while the exec() that happens inside stub-kubectl
was for "/usr/bin/python".
That second Python can't find chunks of its stdlib:
