Update _index.md (#30611)

The run command for a silent Windows Private Location Installation via CLI is incorrect and inconsistent with the required deployment property for the worker configuration filepath.

WORKERCONFIG_FILEPATH has been corrected to the below, as has the filepath recommendation, which should point the the config the user has downloaded via the UI. The service will not install correctly with WORKERCONFIG_FILEPATH.

CONFIG_FILEPATH=<path_to_your_worker_config_file>
