Add a completion-menu table to KEYBINDINGS.md covering the new cmp
mappings (Tab/S-Tab and C-n/C-p to move, C-Space to open, Enter to
confirm, C-e to dismiss), and reword the Neovim summary accordingly.

nvim-cmp ships no default mappings, so the completion menu (including the
path source) appeared but nothing could navigate or accept it. Bind the
usual set: C-n/C-p and Tab/S-Tab to move, C-Space to open, C-e to abort,
and <CR> to confirm with select=false so a bare Enter stays a newline
unless an entry is explicitly highlighted.
