Add thirdperson shotgun animations to weapon_annabelle

[StressedCatInABox]

Is your feature request related to a problem? Please describe. The Annabelle in its current state doesn't have any animations. I run a server that gives the Annabelle to players on spawn, and it's really out of place to see a t-posing player using it.

Describe the solution you'd like Just make the Annabelle use the shotgun's thirdperson animations, if possible.

Describe alternatives you've considered Not many other alternatives, maybe make it have its own animations, but I don't like the sound of that tbh. Alternatively, just fix the whole weapon 💀(don't)

Additional context On the JBDM server, we have the Annabelle as a player item via a console command and a plugin. We also have a custom weapon script, that uses the SniperRounds ammo type, with increased clip size. This encourages players to use the weapon, along with its extra damage, but it's hard to take it seriously with no animations. :( Here's a picture of the annabelle in its current state. Shotgun viewmodel, and no thirdperson animations.

on another note, it doesn't leave bullet marks in multiplayer.
