Remove honeybadger notify from health monitor error_callbacks

[hackartisan]

We've created the health monitor pages in an effort to move away from honeybadger for these kinds of monitoring concerns. Removing these notifications will hopefully reduce the number of honeybadger events we sift through.

Here's an example of one: https://github.com/pulibrary/figgy/blob/7b094cb4a97fa10df6cd01c9d0d4f1cc4780f4aa/config/initializers/health_monitor.rb#L17
