[PATCH v2] docs: use :kbd: role in sphinx docs

[Manos Pitsidianakis]

Sphinx supports the :kbd: role for notating keyboard input. They get
formatted as <kbd> HTML elements in the readthedocs theme we currently
use for Sphinx.

Besides the better visual formatting, it also helps with accessibility
as screen readers can announce the semantics of the <kbd> element to the
user.
