    docs/misra/rules.rst: Fix entry for 20.12 rule
    
    Commit 4cac80e22600 broke the CI cppcheck jobs by adding an entry for
    a rule 20.12 with "Severity" and "Summary" fields placed in reverse order.
    This leads to an error as reported by convert_misra_doc.py:
    No summary for rule 20.12
    
    Fixes: 4cac80e22600 ("docs/misra/rules.rst: add rule 16.6 and 20.12")
