ANSI shell sessions in Sphinx documentation

[kdeldycke]

I just noticed Kitty documentation are made out of Sphinx and the Furo theme.

I want to show Kitty's maintainers my click-extra project, which provides some Sphinx helpers to render shell sessions with ANSI codes properly. With Kitty being a terminal, maybe there are some snippets in its documentation that can benefits from my little utility and lower the maintenance of it.

FYI, I just streamlined and documented the setup of .. click:example:: and .. click:run:: directives at: https://kdeldycke.github.io/click-extra/sphinx.html
