Update readme with usage instructions.

This combines some knowledge from PR #12 which was merged earlier this year, plus comments there, and my own notes from creating a Jenkins node earlier this year. I made a second one now with these instructions.

This needs the following PR: gforcada/ansible-compile-python#27 And another release of that ansible role.

I have registered my new node on Jenkins, but have not yet brought it online. I will do that tomorrow so I can follow up if things go wrong.

The first two jobs have started executing:

• https://jenkins.plone.org/job/plone-6.2-python-3.10/340/
• https://jenkins.plone.org/job/plone-6.0-python-3.13-robot-chrome/367/

The first two jobs have finished successfully!

Here is the build history of this node, which by now has 5 jobs. One of them failed after 10 seconds when trying to install colorama: zipfile.BadZipFile: File is not a zip file. That is probably due to parallel running buildouts. A few lines before, there is a case where it only nearly succeeds:

Getting distribution for 'requests==2.32.3'.
root: Downloading...
Path /home/jenkins/.buildout/eggs/cp313/requests-2.32.3-py3.13.egg unexpectedly already exists.
Maybe a buildout running in parallel has added it. We will accept it.
If this contains a wrong package, please remove it yourself.
Got requests 2.32.3.

So this just seems an initial hiccup.

Meanwhile 13 jobs have run. Next to the failing one I mentioned above, one other failed, because the symlink to Python 3.12 was missing. That may have been while I was running the ansible playbook a second time. I have created the symlink manually now.
