Running GitHub Workflows duplicate events: push and pull_request

[grayside]

The GitHub Workflow template runs for each set of samples on push and pull_request.

Based on my reading of the syntax documentation, pull_request is necessary for forks.

It looks like folks contributing from a branch in the repository would trigger duplicate tests. Looking at some data, I don't see signs of duplicate work but documented points like https://docs.github.com/en/actions/using-workflows/triggering-a-workflow#using-multiple-events indicate that there should be.

Action Items from this issue should be one of:

• Removing push as an event trigger from each config and the template
• Adding an in-line comment to each config and the template explaining why we use both

@sofisl could you provide some insight into why we have both triggering events in the config?
