Wrong compatibility data for ServiceWorkerRegistration (Safari on macOS)

[fyrk]

According to web-confluence.appspot.com, the following properties of ServiceWorkerRegistration are not supported by Safari (on macOS):
getNotifications, navigationPreload, paymentMethod and pushManager

However, according to ServiceWorkerRegistration.json, they are all supported since 11.1 or - in case of .paymentMethod - the support is unknown. It looks like this information was mostly added in #1881, which addressed ServiceWorker support in general.

The following table gives an overview of the incorrect data; all of the following properties are not supported by Safari:

Property of ServiceWorkerRegistration	Supported according to this repository?	Comments
getNotifications	11.1
navigationPreload	11.1	Support for NavigationPreloadManager is currently unknown, this should probably be changed to unsupported as well
paymentManager	unknown
pushManager	1.11	The PushManager interface is correctly marked as not supported

If desired, I can try to create a Pull Request to fix the compatibility data.

Yes please — it’d be great if you could create a PR. If you do, I can commit to reviewing it.
