Action to create notification and set title and content

[sudomain]

Developer TODO (don't remove)

• create new branch. put issue number at start of name
• Create a "Custom notifications" notification channel. Auto-create the channel when NotificationController is initialized. Use default priority for the channel.
• Use existing NotificationModel class and NotificationAdapter.
• Request POST_NOTIFICATIONS permission in ActionUtils
• Specify a timeout that auto-dismisses the notification. Use SliderOptionText and default is 30 seconds. This is optional so also show a checkbox (CheckboxText) to enable/disable this feature.

I'd like to have an action to create a notification and specify a title and content please. The current toasts are nice but are ephemeral.
