Add AD FS support

Is your feature request related to a problem? Please describe.
AD FS support.

Describe the solution you'd like
The SDK should add support for AD FS via prompt=login as stated at https://learn.microsoft.com/en-us/windows-server/identity/ad-fs/operations/ad-fs-prompt-login.

Describe alternatives you've considered
The prompt query parameter on the /authorize call is something that the SDK does not set. The prompt value is set by Azure.Identity/MSAL library, which defaults to prompt=select_account when no login hint is provided and prompt=none when a login hint is provided. As per the guidance at Microsoft identity platform and OAuth 2.0 authorization code flow - Microsoft Entra | Microsoft Learn, MSAL's default of prompt=select_account should be sufficient to allow the customer to use a different account to sign-in rather than automatically using single sign. However, it does appear that this is not the case for certain AD FS scenarios.

Additional context
This feature depends on having configuration of prompt value in Azure.Identity which is currently not supported - https://github.com/Azure/azure-sdk-for-net/issues/38099.

Start by reviewing how the PowerShell SDK builds its /authorize call and the linked Azure.Identity InteractiveBrowserCredential.cs reference. Check the dependency on Azure.Identity issue 38099 before making changes. Done means AD FS scenarios can use prompt=login through the SDK, with the behavior verified against the referenced authentication guidance.
