[docs] [issue35616] Change references to '4.0'.

[Terry J. Reedy]

Terry J. Reedy <tjreedy at udel.edu> added the comment:

After reading Serhiy's explanation, I agree that '4.0' is better than a specific '3.nn'.  I did not realize how much was still left to be done.  We can revisit this when there is a definite removal date.  A literal 'sometime' might be better, but not worth arguing for.  Most of the other occurrences of '4.0' are related to the old unicode API.
