On pull requests, run cypress with only chrome

Allow full cypress runs with all browsers on:
* adhoc workflow_dispatch
* pushes
* schedule

Currently, firefox is very slow, over 40 minutes, while chrome and edge
are under 20 minutes each.  For now, let's get chrome to verify PRs
while we upgrade cypress and try to improve the speed further.
