Add Missing Production Migration Path/Support for Microsoft Entra Application Proxy

[cathay-yu-sage]

Is your feature request related to a problem? Please describe. The Azure AD PowerShell management APIs are being imminently deprecated (https://techcommunity.microsoft.com/t5/microsoft-entra-blog/important-azure-ad-graph-retirement-and-powershell-module/ba-p/3848270). The suggested direct mappings to Graph API equivalents are currently missing support for application proxy and application proxy connector (https://learn.microsoft.com/en-us/powershell/microsoftgraph/azuread-msoline-cmdlet-map?view=graph-powershell-1.0#application-proxy-application-management).

Describe the solution you'd like Ideally, full released, production support for missing application proxy management capabilities before final terminated deprecation of existing available management capabilities relating to the application proxy and connector.

Describe alternatives you've considered An alternate pattern is available via the BETA APIs, but they are not released for production usage and no public timeframe for official release; https://learn.microsoft.com/en-us/graph/application-proxy-configure-api?tabs=powershell

Additional context These management APIs allows for automated configuration and deployment of the Microsoft Entra Application Proxy outside of manually configuring via the Azure Portal UI management..
