Fix Applies to versions for Remote PC Entra SSO article (#8119)

Remove Windows Server 2019 and 2016 from the Applies to banner for the
Remote PC single sign-on with Microsoft Entra authentication article.
Entra SSO doesn't work on those versions, and they contradicted the
article prerequisites (Windows 11/10/Server 2022). Adds a file-specific
appliesto override in docfx.json so only Windows Server 2025/2022 and
Windows 11/10 are listed.
