ntfy integration for alerts

[tetra-archos]

Is your feature request related to a problem? Please describe.

No

Describe the solution you'd like

I would like ntfy integration added for notifications. It should be a pretty simple integration as they support curl, ntfy-cli(their own script) HTTP, Javascript, Go, Python, PHP for posting messages.

Describe alternatives you've considered

No alternatives for me without switching notification servers, or adding another service.

Additional context

ntfy is a well used project with 17.7k stars on github. It would allow for more flexibility for notifications from your app to have it as an option.

To my knowledge, this is already supported via shoutrrr (see here). The only hang-up (for me, anyway) was getting it to use access tokens, which is covered in the shoutrrr repository here.
