v5.22.9

Bug fixes

• Fix a packaging issue when using Carthage, introduced in 5.22.7. Note:
  There is a remaining known issue when updating/building the bugsnag-cocoa
  dependency with Carthage, the project will build three times in Xcode 11 before
  completing successfully. This issue will be resolved in a subsequent patch release.
  #423
• Deprecate config.reportBackgroundOOMs property - designating any app
  termination as a possible error condition can cause a lot of false positives,
  especially since the app can die for many genuine reasons, especially when
  running only in the background.
