Warnings emitted during GitHub Workflow execution

[cweider]

There are many warnings from the actions run in the checks of pull_request. Virtually all relate to deprecation of one kind or another.

The majority of issues relate to:

• GitHub Actions: Deprecating save-state and set-output commands
• GitHub Actions: All Actions will begin running on Node16 instead of Node12

Both of which are of the variety “we’re turning this off in Summer 2023” – which would be bad. Enforcement of Node16 became effective on the 14th of June (with no serious effects) and collective inaction has led the set-state command disabling to be postponed indefinitely (from 31st of May 2023). Nevertheless, the deprecated command should be replaced – it’s best to address these warnings on a schedule we control.
