Updated sort.py

In the last code of sort.py a 'w+' is missing when writing the sorted lists. So I have add it to be in the side of Python 3.

-    The approach taken is explained below. I decided to do it simply.
-    Initially I was considering parsing the data into some sort of
-    structure and then generating an appropriate README. I am still
-    considering doing it - but for now this should work. The only issue
-    I see is that it only sorts the entries at the lowest level, and that
-    the order of the top-level contents do not match the order of the actual
-    entries.
+    with open("README.md", "r") as read_me_file:
+        read_me = read_me_file.readlines()  # Leer todas las líneas
 
-    This could be extended by having nested blocks, sorting them recursively
-    and flattening the end structure into a list of lines. Revision 2 maybe ^.^.
