skip the gather_results step for builds if scheduled action (#248)

#228 added a summary step to the build checks. This always runs, even if the build checks are skipped (scheduled builds on forks). Because no builds have passed, this returns a false fail.

This change causes the workflow to only run the summary step if it is not triggered by a schedule. This will have no effect on scheduled runs on the main repo because the summary step is not used there - it is only used as a branchy protection requirement.
