com.unity.xr.arcore 6.0.0-pre.5 Package Notes

During builds, reference image libraries with images that score lower than 75 with the 'arcoreimg' tool will produce a report as a console warning. Refer to Google's arcoreimg tool documentation for more details.

Changed AR Foundation dependency version from 6.0.0-pre.4 to 6.0.0-pre.5.
Changed the format of the ARCore display matrix returned by `XRCameraFrame.TryGetDisplayMatrix` to be row-major and to match the format of ARKit's display matrix. The ARCore display matrix also now incorporates flipping the y-axis of the image before rendering, which was previously handled by the ARCoreBackground shaders.
Changed ARCoreBackground.shader and ARCoreBackgroundAfterOpaques.shader to correctly render the background using the new display matrix.
Changed the image tracking documentation to reference the newly updated [Use reference image libraries with AssetBundles](xref:arfoundation-image-tracking#use-reference-image-libraries-with-assetbundles) manual in AR Foundation.
Changed the project validation rules to remove a warning if this plug-in was not enabled for the Android build target. There are legitimate reasons to build for Android without enabling the ARCore plug-in, so this warning was not helpful.

Fixed issue ARFB-322 where an image library that had an image(s) score too low with the arcoreimg tool, or fail to score at all, would cause a crash at runtime.
