Adding webxr support VideoPlayer/plugin.js

[glennpierce]

Hi I was thinking of adding webxr support to the player using the "three" lib

Is editing
https://raw.githubusercontent.com/jellyfin/jellyfin-web/refs/heads/master/src/plugins/htmlVideoPlayer/plugin.js
a workable approach ?

I want to make sure its feasible before looking at the code too much and how to add new plugins etc.
