Bump airbrake from 7.4.0 to 11.0.3

Note we're using `config.performance_stats = false` because enabling it
was causing a huge performance hit; pages were about 2-4 times slower
and some tests failed since requests took longer than Capybara's default
max wait time. Errbit also recommends disabling this option since
Errbit doesn't handle performance stats.
