Support action fire-dom-event

[VDRainer]

Is your feature request related to a problem? Please describe.
browser_mod switching to fire-dom-event away from call-service for popups, toasts, etc., see release notes: https://github.com/thomasloven/hass-browser_mod/releases/tag/1.3.0

Describe the solution you'd like
Implement support for action: fire-dom-event in tap_action and hold_action

Describe alternatives you've considered
As of now browser_mod can still be used with call-service action, but might be phased out soon

@kalkih I see tap_action for fire-dom-event any chance for adding hold_action also?
