Medium: Validate and remove invalid blogs from Zowe publication

[balhar-jakub]

Validate the blogs and propose removal of the old ones? (Some blogs are old and outdated - should we perform a review and remove those that may lead the reader down an inaccurate (for present day) path? In general, what do others do with blogs that are old & outdated? Do we assume the reader realizes this via the date and they search for something more recent?)
