[dependabot-preview]

Bumps airbrake from 9.3.0 to 9.4.4.

Changelog

Sourced from airbrake's changelog.

[v9.4.4][v9.4.4] (September 18, 2019)

• Fixed broken bundle exec rake airbrake:deploy
  (#1003)

• Introduced Airbrake::Rails.logger, which replaces the old way of configuring
  Rails apps. The logging setup becomes as simple as
  (#1003):

  c.logger = Airbrake::Rails.logger

• Exceptions occurring in current_user no longer crash the library
  (#1007)

• Rails controller helpers started supporting the block argument for notifying
  (#1010)

[v9.4.3][v9.4.3] (August 8, 2019)

• Rails: report unauthorized requests properly. Instead of 0 HTTP code the
  library sends 401 now (#997)

[v9.4.2][v9.4.2] (August 7, 2019)

• Rails: engine routes are now being marked with the engine name prefix
  (#997)

[v9.4.1][v9.4.1] (August 5, 2019)

• Started depending on airbrake-ruby
  v4.6.0 and
  higher (#995)
• Disabled SQL query collection by default because it's in alpha
  (#995)

[v9.4.0][v9.4.0] (July 29, 2019)

• Added the new max_retries optional parameter to
  Airbrake::Sidekiq::RetryableJobsFilter:

  Airbrake::Sidekiq::RetryableJobsFilter.new(max_retries: 10)

  It configures the amount of allowed job retries that won't trigger an Airbrake
  notification. After it's exhausted, Airbrake will start sending errors again
  (#979)

• Rails: started logging to airbrake.log by default. This affects only new
  Rails apps. Apps that already use Airbrake have to update the logger manually
  (not mandatory). Please consult README for instructions
  (#986)
