Updating pipeline to run E2E tests for ooproc

This PR addresses running the E2E tests for the chat completion dotnet isolated scenario. In order for isolated to work, the worker needs to build its own local package of web jobs to pick up the latest changes. The pipeline creates a test package called Microsoft.Azure.WebJobs.Extensions.OpenAI.99.99.99-test.nupkg and puts it into a local feed called NuGetPackagesLocal. The worker then consumes these changes and runs the E2E tests as expected.

I also removed the in-proc sample project and tests for chat completion, since going forward we would want users to only use the isolated model.

try providing model name like it is done in in proc sample to run these tests - https://github.com/Azure/azure-functions-openai-extension/blob/main/samples/chat/csharp-inproc/ChatBot.cs#L43C8-L43C113

the tests run on Azure Open AI, it expects the deployment name as model name.

verify the docker run and test (commands available in the pipeline), you would need docker desktop to build the image,
in your local system with three keys and their values in local.settings.json -
"AZURE_OPENAI_KEY": "",
"AZURE_OPENAI_ENDPOINT": "",
"AZURE_DEPLOYMENT_NAME": ""

One small blocker for me to make it easier for users to successfully run the sample.
