This change refactors the SortedMap type in the fmtsort package from using
two parallel slices for keys and values to a single slice of structs. This
improves code clarity and reduces the complexity of handling map entries.
Affected files and their respective functions have been updated to work
with the new structure, including adjustments in fmt/print.go and
text/template/exec.go to iterate over the new map representation.
