When running the net - identity - tests CI pipeline, there is an error preventing the CI from completing successfully.

The error is in the file:
https://github.com/Azure/azure-sdk-for-net/blob/main/sdk/identity/test-resources-post.ps1

And the error details are:
/usr/share/dotnet/sdk/9.0.203/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.CrossTargeting.targets(31,5): error NETSDK1129: The 'Publish' target is not supported without specifying a target framework. The current project targets multiple frameworks, you must specify one of the following frameworks in order to publish: net8.0, net9.0 [/mnt/vss/_work/1/s/sdk/identity/Azure.Identity/integration/WebApp/Integration.Identity.WebApp.csproj]

To validate the fix, the net - identity - tests pipeline can be run from the PR by creating a comment with the following text:

/azp run net - identity - tests

This issue is considered complete when the net - identity - tests runs successfully.
