Clarify supported Python runtime language version about antlr4 HOT 4 OPEN

It is unclear what it could be because the tester uses the latest available.

Thanks for the response @kaby76, it's raised some further questions.

The plugin itself recommends setting an explicit version: (we recommend always setting Python version explicitly using the python-version or python-version-file inputs).

Where'd you find that line? The readme for the Python target doesn't seem to have that text in it and I'm unsure what a 'plugin' is in the ANTLR ecosystem. Also don't get any code matches on a Github search.

In addition, to properly qualify a version range, you need to test each and every version in a range of versions in a test matrix in Github Actions workflow. ... I don't test a range because it takes a long time to do this testing with each PR. And it can be expensive.

Hmm yeah having a look at the GitHub actions it looks like this repo is using one giant sequential job for the bulk of the Workflow. I feel like there'd be huge benefit in making a larger number of small jobs, but that's probably a different ticket.

The kind of code I'm proposing removal of (if 3.6 is minimum supported) is blocks like

Sorry, it is from https://github.com/actions/setup-python , the first big paragraph under "Basic usage".

Yes, validating the supported versions of a runtime environment is another problem. The change in the Antlr source code is also something that needs to be fixed with the correct value or removed.

Ah I misunderstood; thought you were talking about ANTLR suggesting pinning Python.
