move back vertical button_type to its own section
move back vertical button_type to its own section

inline/horizontal is a 1xN matrix where vertical is a Nx1 so splitting it as it was before.  Still on the previous version reply_markup was inside the loop and we keep it outside the loop here.  We keep list comprehension for consistency on inline and vertical but if not clear I can put the for loop with appends
