    Update supported_enctypes documentation
    
    In commit 38a31852c3e58f6e2f6b3b035a87f817d1db5537, the aes-sha1
    enctypes became the only defaults, but the documentation was not
    updated.
    
    (cherry picked from commit 56982b666e10fbb47c1fb70947b3e176c9a5e2d1)
    
    ticket: 8834
