[Doc]: create sphinx configuration that skips on dependencies #24414
Description
Documentation Link
https://matplotlib.org/devdocs/devel/documenting_mpl.html#building-the-docs
Problem
Latex, graphviz, and inkscape are kind of heavy dependencies to install if you're working on documentation changes that don't depend on latex, graphviz, or inkscape - like most of the gallary and a lot of the tutorials.
Suggested improvement
Can we adopt a sphinx equivalent of skipif? Two ways of doing this are: (edit: these are both sphinx directives)
| ..ifconfig | ..only | |
|---|---|---|
| pro | arbitrary conditions as part of the directive | have to explicitly enable with -t flag |
| con | unclear how to disable | have to maintain list of tags/conditions |
