Link to Jellyfin/Emby/Plex in "Now available" mail notification

[Rollbacke]

Description

After approved and downloaded, currently, the user receives an email that said that their requested media is available.
The link currently in the email redirects to Jellyseer.

Desired Behavior

I think a link to Plex/Jellyseer/Emby (to Films/Series/whatever requested) would be more useful for the user at this point than being redirected to Jellyseer.
For the user, it's fine; they've made their request (which has been approved), and there's no need for them to see that it's available on Jellyseer when they've already received a message saying it's available.
So, let's get straight to the point for the user: the page to watch their movie/episode.

Additional Context

Jellyseer 2.7.3
