az storage blob directory is implicitly deprecated

[Enter feedback here]
Document indicate this command is still preview but when I executed it shows the following message.
"This command is implicitly deprecated because command group 'storage blob directory' is deprecated and will be removed in a future release. Use 'az storage fs directory' instead."

Should we update Note comments?
