Add simple MQTT messages to available notifications.

[JonnyJonnster]

Description

I'd very much like to integrate Seerr into my Home Assistant stack and, for example, flash some lights behind my TV if Seerr recognizes new episodes on my media server.

Desired Behavior

To be able to send MQTT messages (QoS 0 could be enough imo) onto a predefined topic on a predefined server (could be in local network), in addition to E-Mail, webhook, etc.

This can already be done using Seerr's existing webhook notifications.

For the Home Assistant example, MQTT isn't required at all:

Seerr → Webhook → Home Assistant → lights / automation

Home Assistant can receive the webhook from Seerr and directly flash the lights behind the TV, change their colour, send a notification, or trigger any other Home Assistant action.

So for the use case described here, Seerr's existing webhook support already provides the required functionality. Native MQTT support would only be needed if someone specifically wanted Seerr to publish directly to an MQTT broker without Home Assistant handling the event.
