Check if job yaml file exists

[mauritsvanrees]

In meta.yml.j2 we have:

jobs:
{% for job_name in jobs %}
  %(job_name)s:
    uses: plone/meta/.github/workflows/%(job_name)s.yml@%(ref)s
  {% if job_name == 'coverage' and os_dependencies %}
    with:
       os-packages: '%(os_dependencies)s'
  {% endif %}
{% endfor %}

So if job_name is test, this will try to use our .github/workflows/test.yml, which since recently no longer exists, because people should use the test-matrix workflow instead.

That is what I fix here in diazo: plone/diazo#97

In the Python code we could check if the yaml file exists. But probably only if ref is not explicitly set.

Problem: this can probably work when you use a checkout of plone.meta, as the workflows are in the repository. But when you use a normal pip/uv install of plone.meta, those workflows files are not available.

Alternatively, we could simply add a list of known and accepted job names, and compare the user-supplied names with that.

Yes, the second option looks much simpler 👍🏾
