Mention of deprecated Volume Types

travnewmatic

not sure if its ok to copy/paste contents of LFS course materials here but

https://trainingportal.linuxfoundation.org/learn/course/kubernetes-fundamentals-lfs258/volumes-and-data/volumes-and-data?page=4

lists some items which are no longer part of kubernetes

not a huge deal, and its interesting to see! but not sure if it should still be part of the course

thanks for all the hard work! really enjoying it so far!
