Add support for MyST-NB Glue functionality in jupyter-manim

[mscharling]

Hi,

I’d like to suggest adding support for using jupyter-manim with MyST-NB’s glue functionality to embed manim-generated content (animations, images, etc.) inside MyST admonitions. This would allow users to include manim outputs within notes, examples, exercises, and other structured elements for better visual clarity.

Use Case: In my case, I use admonitions to create examples and exercises for my students. It would be very helpful to have manim-generated visualizations embedded directly within these sections using glue, to make the content more engaging and interactive.

Best,
Martin
