Restrict benchmark auto-push to scheduled runs only

Previously, workflow_dispatch runs on master also auto-pushed
benchmark results to gh-pages. This allowed one-off manual runs
with arbitrary runners/configs to create permanent graph entries
on the benchmark dashboard, cluttering it with near-empty graphs
that would never receive new data points.

Restrict auto-push to only schedule events so that only codified
benchmark configurations in the schedule matrix produce persistent
tracking data.
