[issue20351] Add doc examples for DictReader and DictWriter

[Charles-Axel Dein]

New submission from Charles-Axel Dein:

IMO csv.DictWriter and csv.DictReader provides a nicer interface for complex CSV file. I see some people reinventing the DictReader and DictWriter pretty frequently, because when they rapidly scan the documentation all examples are about csv.reader and csv.writer.

This patch adds examples.
