[CI] Remove trigger for "test scenarios" pipeline
[CI] Remove trigger for "test scenarios" pipeline

This was added initially as a placeholder for future, post-e2e testing
pipeline work. We'll get around to that at some point, but in the
meantime, all this does is generate failure messages for us in Slack,
because there isn't actually a pipeline yet to trigger.
