Helm of Balduran - Stun Immunity Fix

The "Stun Immunity" passive on the Helm of Balduran doesn't work as intended, because it only covers one specific instance of the "Stunned" status, while actions like Mind Blast, Stunning Gaze, and Stunning Strike set up the "Stunned" status a bit differently. All I did was edit the Stun Immunity passive to include all forms of stunned via the status group.

I tested this in the toolkit using all the actions mentioned above without issue, but I obviously can't test against things that aren't in the toolkit. So it should work, but rare edge cases (like homebrew spells or actions) might not work if they use a different status group.

Thanks to the kind folks in the BG3 Modding Community for helping me narrow down what I needed to do to fix this!
