com.unity.xr.arfoundation 3.1.5 Package Notes

Updated ["Configuring the AR Camera background using a Scriptable Render Pipeline"](../manual/ar-camera-background-with-scriptable-render-pipeline.html) documentation for further clarity on setup steps.
Updated ["Copying the Camera Texture to a Render Texture when accessing the camera image on the GPU"](../manual/index.html#copying-the-camera-texture-to-a-render-texture-when-accessing-the-camera-image-on-the-gpu) documentation to use a 'Command Buffer' instead of a 'Graphics.Blit()' to fix an issue where blit would not work on certain devices.
