feature render Driver in notebooks

[zilto]

Simple quality of life improvement to directly call driver.display_all_functions(). The change was inspired by the logic found in Jupyter Magic.

This simply propagates the "render attribute" of the graphviz.Digraph object returned by driver.display_all_functions() so it should be robust.

Changes

• added ._repr_mimebundle_() to Driver class

How I tested this

• tests succeeded locally
• intended behavior works in Jupyter notebooks (browser interface) and VSCode notebooks

Looks good. Can you make the PR message the body of the commit for this please, since the PR message provides a good explanation of why that would be useful to have in the commit. Thanks!
