Glossary: Change SoS link to documentation and describe origin in description. (Was: Change source for SoS to Wayback Machine link) (#81178)

* Glossary: Change source for SoS to Wayback Machine link

The page seems to have disappeared in the currently archived version of Jason Zander's blog at https://learn.microsoft.com/en-us/archive/blogs/jasonz/ - so replace it with a Wayback Machine link to an archived version.

* Link to official documentation for SOS instead and mention origin of name in the description.
