vim-patch:partial:9.1.1955: sort() does not handle large numbers correctly (#36840)

Browse Source 
Problem:  sort() does not handle large numbers correctly
          (Igbanam Ogbuluijah)
Solution: Don't truncate the return value of tv_get_number_chk()
          (Yegappan Lakshmanan)

closes: vim/vim#18868

04794efe12

Use a Lua test for now, as the Vimscript test uses tuples.
