[Feature Request] Implement backup api endpoint

[tommyalatalo]

Description

Lidarr/Sonarr/Radarr have api/command endpoints which allow the user to dump a backup of the service settings. This would be very nice to have in jellyseerr as well so that it's possible to schedule periodic backups programatically.

An example of running the api/command to execute a backup with httpie:

      config {
        image = "alpine/httpie"

        args = [
          "--ignore-stdin",
          "POST",
          "http://sonarr.service.consul:${SONARR_PORT}/api/command",
          "X-Api-Key:${SONARR_API_KEY}",
          "name=Backup",
        ]
      }

Desired Behavior

Implement the api/command endpoint as mentioned in the description so that backups can be made on-demand by sending a POST request.

This sounds like a good feature request for Overseerr as it is a core overseerr functionality rather than specific to jellyfin/emby 🤔 Once then integrate I'll pull it to jellyseerr :D
