Show complete Khoj keybindings when initiate search in Emacs

- The keybindings to select search types was previously confusing as
  it only highlighted the final symbol to press (the C-x was shown but
  it wasn't made apparent that it had to be pressed before)

- Previously some keybindings unrelated to khoj were also being shown
  in the which-key popup. Now only the khoj keybindings are visible
