To reduce noise in Sentry,
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/28058 grouped a
number of exceptions into a single event. However, this is not helpful
to identify patterns in statement timeouts, which should be grouped
based on controller and action. Remove `ActiveRecord::QueryCanceled`
from this list to avoid this grouping.
