ideally, we should detect the presence of these files and use that to key off
showing the results, not preconfiguring that

acknowledged. Going to keep it as is at first, so I can first enable on FYI bots
only. And if everything works as intended, Ill change it to detect presence of
these files automatically instead of having to configure render_results_dir for
every bot.
