Updated the description of max_delta parameter
I don't see "absolute" anywhere in the documentation.  Instead, the docs refer to the `adjust_brightness` documentation, which would probably be the place to change if anything. Hi @sushreebarsa Can you please check @cantonios's [comments](https://github.com/tensorflow/tensorflow/pull/62402#issuecomment-1813075282) and keep us posted ? Thank you!




The documentation currently states that the max_delta parameter controls the maximum absolute change in brightness of images. However, the max_delta parameter actually controls the maximum relative change in brightness of images. This means that the actual change in brightness will depend on the range of values in the input image. So, I have updated the description for the max_delta parameter. Could you please have a look and do the needful? 
Thank you!
