[Accessibility] Accessible View does not get dynamically updated in Jupyter Notebook cell output

[jooyoungseo]

Type: Bug

CC @meganrogge

When screen reader users augment current Notebook cell output in Accessible View via alt+F2, dynamic content does not get updated in the buffer, such as downloading progress on pip/conda packages and any computational progressive print.

@jooyoungseo not sure how complicated this would be to do.

@amunger , we do this for the terminal. Thoughts?

I'll have to take a look at how the terminal is doing it, but I don't see why we wouldn't be able to do something similar for notebook outputs.
