When streaming pipelineRun or taskRun logs, closing the stop channel to terminate the informer was causing "Failed to watch" error messages to be logged with "context canceled". This was noisy and confusing
for users even though it was expected behavior during intentional
shutdown.
This patch add custom watchErrorHandler function that filter out context.Canceled errors while passing other errors to the default handler. This prevents the error log messages when the CLI intentionally stops watching after a run completes.
