add check in code_edits.lua before setting the line numbers for the window
setting 'show_line_numbers = false' will disable the line numbers
when setting show_line_numbers = false, it would be advisable to also set the popup_window.win_options.foldcolumn = "0", to get clean experience, but I left that option for the users.
