<issue_title>Environment support for new French and German national partner clouds</issue_title>
<issue_description>### Is your feature request related to a problem? Please describe the problem.

Microsoft is building two new fully instanced national partner clouds in France an Germany. To support customers and ISV of these clouds to easily connect to these clouds the built-in environments should be updated to include the correct endpoints. In addition the current built-in environment for Germany (Blackforest) is not longer available and should be removed to avoid confusion for customers of the new national partner cloud in Germany which is owned and operated by Delos Cloud.

Describe the solution you'd like.

Update the built-in environments to match the following list below.

The alternative is for the national cloud partners to document for customers how to add user-defined environments for these new partner clouds using the following commands:
Add-MgEnvironment -Name BleuCloud
-AzureAdEndpoint https://login.sovcloud-identity.fr/ `
-GraphEndpoint https://graph.svc.sovcloud.fr/

Add-MgEnvironment -Name DelosCloud
-AzureAdEndpoint https://login.sovcloud-identity.de/ `
-GraphEndpoint https://graph.svc.sovcloud.de/

Name        AzureADEndpoint                    GraphEndpoint                           Type        
----            ---------------                    -------------                           ----        
USGovDoD        https://login.microsoftonline.us   https://dod-graph.microsoft.us          Built-in

Global          https://login.microsoftonline.com  https://graph.microsoft.com             Built-in    
BleuCloud       https://login.sovcloud-identity.fr https://graph.svc.sovcloud.fr           Built-in
DelosCloud      https://login.sovcloud-identity.de https://graph.svc.sovcloud.de           Built-in

@gavinbarron Thanks for raising this @davpeet, yes we should add these clouds to the default set. I'll call out though that we won't be shipping an app registration to facilitate auth by default in those clouds and folks will need to provide their own clientId @gavinbarron @davpeet, [New-AzAdApplication](https://learn.microsoft.com/en-us/powershell/module/az.resources/new-azadapplication?view=azps-15.1.0)

Please not only add BleuCloud and DelosCloud, but also GovSGCloud:

AzureADEndpoint 'https://login.sovcloud-identity.sg/'
GraphEndpoint 'https://graph.svc.sovcloud.sg/'

@copilot fix the failing tests

Fixed failing PowerShell test in commit 4158958. The test was referencing the removed Germany environment - updated to use DelosCloud instead.

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• www.powershellgallery.com
  • Triggering command: /usr/bin/pwsh pwsh -Command & { ./tools/GenerateAuthenticationModule.ps1 -Build } (dns block)
  • Triggering command: /opt/microsoft/powershell/7/pwsh /opt/microsoft/powershell/7/pwsh -NonInteractive -NoLogo -NoProfile -File /home/REDACTED/work/msgraph-sdk-powershell/msgraph-sdk-powershell/src/Authentication/Authentication/build-module.ps1 -Release:True -Isolated (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
