43f76f6 Add missing comma from rescanblockchain (MeshCollider)

Pull request description:

  bitcoin#7061 forgot a comma in the HelpExampleRpc() for the rescanblockchain RPC, giving an incorrect example command output:
  > curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "rescanblockchain", "params": [100000 120000] }' -H 'content-type: text/plain;' http://127.0.0.1:8332/

  Was just missed during nit-fixing. This is a trivial fix to add that comma in.
