[PATCH 3/4] tools/misra: fix skipped rule numbers



Currently the script convert_misra_doc.py is using a loop through
range(1,22) to enumerate rules that needs to be skipped, however
range function does not include the stop counter in the enumeration
ending up into list rules until 21.21 instead of including rule 22.

Fix the issue using a dictionary that list the rules in misra c2012.
