Update "bug occurs when" section (#878)

There are 3 main categories we can see for bug reports, exporting to
YAML, submitting to Argo (which is actually likely related to
YAML/`to_dict` exporting), and running on Argo with the Hera runner, now
that it is graduating from experimental. Added an "Other" option as well
for reporter to explain.
