There are problems with running this job on Noble due to Python 3.12
incompatibities with our ancient ansible-lint setup. Pin the job back
for now so taht we can land things after the Noble default nodeset
change.
Followups will deal with the ansible-lint setup to make it more
resilient to newer python (or possibly remove it or reduce its scope).
