[PP] 'object' is a reserved keyword as of PHP version 7.2 and should not be used in namespaces

Problem/Motivation

The module use the reserved word "object" as part of namespace, and it's generate a warning compatibility with php 7+.

run ./vendor/bin/phpcs -p jsonrpc/ --runtime-set testVersion 7.4 --standard=PHPCompatibility --extensions=php,module,inc,install,test,profile,theme

Proposed resolution

Change the name from "Object" to "JsonRpcObject", the same happened with the json api core module, you can check here: https://www.drupal.org/project/jsonapi/issues/2971040
