Hello,

I'd like to enhance the docs of this plugin and create a PR for that.

However, I've realized that there is a naming inconsistency between GitHub and Bitbucket which is super confusing.

• In GitHub, the trait is called 'notificationsSkip'.
  https://github.com/jenkinsci/skip-notifications-trait-plugin/blob/ffaa9a99b850ec84a20372150acd735a80016bb2/src/main/java/org/jenkinsci/plugins/github/notifications/NotificationsSkipTrait.java#L66
• In Bitbucket, the trait is called 'skipNotifications'.
  https://github.com/jenkinsci/skip-notifications-trait-plugin/blob/ffaa9a99b850ec84a20372150acd735a80016bb2/src/main/java/com/cloudbees/jenkins/plugins/bitbucket/notifications/SkipNotificationsTrait.java#L59

Not sure if that intended or there are any constraints that force that naming inconsistency.

Thanks
