This PR adds docfx to the CI to target documentation for the
N64FlashcartMenu and updates the libdragon submodule.
It also adds a number of menu improvements.

Will eventually stop us from being lazy, however as the project is very
much WiP,
Currently the CI only runs it to show what warnings need to be "fixed".
In future, it needs to "error" when things are incorrect AND deploy to
the WIKI.
