Fix table colliders in toyroom scene
In the Toyroom scene, unless i run the simulation on CPU (env_cfg.sim.device = "cpu") the objects fall through the table.
Changing the collider approximation from convex-hull to the simpler bounding-cube fixes the issue. Since the parts of the table are rectangular, this doesn't change the shape of the colliders in a meaningful way.

Ah, sorry, didn't realize that it's in draft (first time I try PRs on Hugging Face π ) Thank you for checking the PR! I published it now. It should be ready to merge.
