Merge bitcoin/bitcoin#28291: rpc: removed StrFormatInternalBug quote delimitation

6e8f6468cb removed StrFormatInternalBug quote delimitation (Reese Russell)

Pull request description:

  This PR rectifies an unnecessary set of quotes delimiting the contents of  ```StrFormatInternalBug```. This is a follow up to MarcoFalke https://github.com/bitcoin/bitcoin/pull/28123#discussion_r1297191493.  The method of action was to remove the escaped quotes that were a part of strprintf. A single functional test case was modified to reflect the new output format.

  ```STR_INTERNAL_BUG``` was applied to https://github.com/bitcoin/bitcoin/pull/28123 in ```std::string RPCArg::ToString(const bool oneline)``` in ```rpc/util.cpp```

  The results can be seen below.
