Subject: [PATCH] Add shouldIgnoreDetection check for DetectionType.Bone

This commit updates the cheat detection logic to allow ignoring specific weapons for DetectionType.Bone.

- Modified Detection.cs to include the shouldIgnoreDetection check for DetectionType.Bone, similar to how it's handled for Recoil and Chest detection types.
- Updated AnticheatConfiguration.cs to add an entry for DetectionType.Bone under Game.IW4 in the IgnoredDetectionSpecification, allowing you to configure weapon regexes to ignore for this detection type.
