Intent to ship: Notification.actions

[Kagami Rosylight]

As of 2026-04-22 (I'm late, sorry) I intend to turn on web notification actions support by default. It has been behind dom.webnotifications.actions.enabled. Chrome has shipped it, Safari not yet.

Bug to turn on by default: https://bugzilla.mozilla.org/show_bug.cgi?id=1959931

Standard: https://notifications.spec.whatwg.org/

Intent to Prototype Thread: https://groups.google.com/a/mozilla.org/g/dev-platform/c/0yo4hRuOVWQ/m/2LwlMaD0AAAJ, Android support has been included since then.
