Issue Description
According to the AzureFunctionApp@2 documentation: https://learn.microsoft.com/en-us/azure/devops/pipelines/tasks/reference/azure-function-app-v2?view=azure-pipelines there is no support for DOTNET-ISOLATED|NET48 even though it is supported by azure functions, see the supported versions section here: https://learn.microsoft.com/en-us/azure/azure-functions/dotnet-isolated-process-guide?tabs=hostbuilder%2Cwindows#supported-versions and https://learn.microsoft.com/en-us/azure/azure-functions/migrate-version-3-version-4?tabs=netframework48%2Cazure-cli%2Cwindows&pivots=programming-language-csharp#choose-your-target-net-version
Even though the AzureFunctionApp@2 does not support .NET Framework 4.8 isolated worker the function app is created as .NET Framework 4.8, but there is a mismatch between the expected payload and the runtime.
We've noticed that your function app (THE_FUNCTION_APP) is configured with the FUNCTIONS_WORKER_RUNTIME setting as "dotnet-isolated", but expected value for the deployed application payload is "CSharp". This is an unoptimized state which limits performance and may impact application reliability. To help detect this, you may now see the AZFD0013 event raised at the Warning level in your logs. This will be raised to Error level in a future update. To ensure your app can run properly, for its current payload, you should set the FUNCTIONS_WORKER_RUNTIME value to "dotnet". You must also update any deployment automations you have, such as templates or CI/CD pipelines, so they specify the correct value as well. Please see https://aka.ms/functions-invalid-worker-runtime for more information.
FUNCTIONS_WORKER_RUNTIME is set to dotnet according to the guide (linked above) for creating a dotnet-isolated .NET Framework 4.8.
