Added PATCH method to CORS headers (#11066)

Added PATCH http method to access-control-allow-header-methods header because there are now PATCH endpoints exposed in the API.

See https://github.com/comfyanonymous/ComfyUI/blob/277237ccc1499bac7fcd221a666dfe7a32ac4206/api_server/routes/internal/internal_routes.py#L34 for an example of an API endpoint that uses the PATCH method.
