Look into STL model support for MDX files

GitHub allows rendering 3D models via [STL descriptions](https://docs.github.com/en/get-started/writing-on-github/working-with-advanced-formatting/creating-diagrams#creating-stl-3d-models). There's got to be a way to use this in Docusaurus/MDX as well.

Such a feature would come in handy. Currently images have to be created and tracked as binary files, which isn't ideal.
