nvim: Update +show mode mappings and descriptions

Mappings preceded by <leader>s 'show' something so removed a lot of the 'toggle'
wording from their descriptions.

Subsumed the toggleterm toggles under this menu since they 'show' a term window
(lazygit or ipython).
Changed Aerial mappings to show navigator by default (`<leader>so`) and the
sidebar outline only on capital version (`<leader>sO`) since this mapping is
used less often.

Removed broken molten-image setup.
