[OM] Windows omitted from Support Operating Systems for Ops Manager 5.0 Agent

Problem:
Ops Manager System Requirements documentation's "Operating Systems Compatible with the MongoDB Agent" does not include any versions of Windows. However, in that same section, a sentence appears to contradict this by indicating support for MongoDB deployments Windows:

MongoDB Agent still supports managing MongoDB deployments that run on Windows 2016, 2019, 2020.

melissa.plunkett confirmed that the MongoDB Agent is still supported on Windows for Ops Manager 5.0.

Recommended Change:
Include supported versions of Windows platform in the table of supported Operating Systems for the MongoDB Agent in Ops Manager version 5.0.
