[CI] Remove imageio-ffmpeg from dependencies.

[0mdc]

Motivation and Context

The imageio-ffmpeg dependency is not strictly required to run habitat-sim.
This package depends on libva, which depends on libgl, libglx, libegl and libglvnd.
Those 4 last packages may conflict with Linux packages, causing the OpenGL front-end libraries to fail to communicate to the OpenGL backend.
This error may occur:

GL::Context: cannot retrieve OpenGL version: GL::Renderer::Error::InvalidValue

How Has This Been Tested

Tested locally on a new conda environment.

I deprecated the relevant features. This was really a hold-over from the Colab age. We wanted to write the videos as fast as possible to make the cells more interactive. Good to remove if it is causing dependency mixups and friction for folks.

The failing test indicates that we need to add a lab refactor which is now live in facebookresearch/habitat-lab#2117

Re-running the tests after merging the downstream lab refactor.

I am encoutering the same problem with v0.3.2. How could I fix it?

Fix it by update viz_utils.py as in in commits and also remove all libva, libgl, libglx, libegl and libglvnd in conda env/lib/ path
