[FEAT] Add and/or change discord commands to work with multiple instances of Radarr/Sonarr

[Mr-Simplicity]

Describe the solution you'd like
The option to both change and add custom commands. To point to a second instance of Sonarr. I keep 2 instances, 1 for Anime and another for everything else. Helps keep them separate and without having to make sure everything gets tagged properly every single time.

Also to be able to config the commands from "series" to "TV Shows" and then add a 3rd for "Anime" that points to the second instance of Sonarr.

I know with the current config I can easily point all the variables to a second instance but still need the option to add that 3rd discord command.

Describe alternatives you've considered
Other than installing a second instance of Doplarr, which without being able to change the commands, it would do absolutely nothing.
I could just merge my Instances into 1 but that would be way more of a headache as I really like keeping them entirely separate.
