[test-quarantine] Quarantine ShutdownTests.ConfigurationChangeForcesChildProcessRestart

[github-actions]

Quarantines Microsoft.AspNetCore.Server.IIS.NewShim.FunctionalTests.ShutdownTests.ConfigurationChangeForcesChildProcessRestart due to intermittent connection-reset failures observed when IIS kills the old worker process during a child process restart, seen across 2 CI builds on main over the past 30 days.

Failure Summary

The test verifies that when web.config is modified, the IIS ANCM (ASP.NET Core Module) restarts the out-of-process worker. During the restart, if an HTTP request arrives while the old process is shutting down and the new process has not yet started listening, the OS forcibly closes the connection (SocketException 10054). The LoggingHandler in the test infrastructure attempts to buffer the response body for logging, but the connection is torn down mid-read, producing HttpRequestException: Error while copying content to a stream.

Failed 2 times over the past 30 days. Most recent failing build: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1533151&view=results

Observed in builds: 1533151, 1531282.

Associated issue: #68150

A maintainer or contributor can add the no-quarantine-for-30-days label to this PR to tell the workflow not to touch this test again for 30 days.
