Not all event metrics on "events" pings get event monitoring dashboard links

[chutten]

If you load https://dictionary.telemetry.mozilla.org/apps/firefox_desktop/metrics/nimbus_events_enrollment you'll find it is sent on both the "background-update" and "events" ping. Since it's sent on the "events" ping, it should get a link that says Event Monitoring Dashboard for the enrollment event, like privacy.ui.fpp.click.checkbox does.

I'm not sure why. It looks like the code properly iterates through the set of pings and should, when checking the "events" ping, get the appropriate link.
