rpcdoc: Remove redundant type from description #18258

1. 
   MarcoFalke commented at 2:33 pm on March 4, 2020: member

   The RPC docs are now enforced to specify the json type of the args and results at compile time. However, some help texts contain the type twice. (E.g. #17809 (review) ). The duplicate type in the description should be removed.

   Duplicates can be found with this command:

   0git grep --extended-regexp  'RPC.*(ARR|OBJ).*json (array|object)' src/rpc/ src/wallet/rpc*
   

   Useful skills:

   Basic understanding of how to compile and run Bitcoin Core.
