add annotation that impacted algorithm used in Akrouda sort tests (#2…

…5993)

This PR adds an annotation to a couple of the Arkouda graphs.

(noted by @jeremiah-corrado): For the sorting tests, the historical
behavior was buggy (i.e., for real-valued arrays we were completely
ignoring the algorithm argument and always used the LSD algorithm).
After Bears-R-Us/arkouda#3602 (merged on 8/7),
we are now using the algorithm argument, so the LSD and MSD lines have
different performance.
