The `test/cqlpy/cassandra_tests/validation/entities/json_test.py::testJsonOrdering` was failing because of differences between Cassandra and Scylla in printing JSON floating point values - e.g. Cassandra prints 30.0, where Scylla prints 30. Both are valid, so in this patch, instead of comparing strings, we compare parsed JSON using `EquivalentJson`. Fixes #28467 Closes scylladb/scylladb#28924
