Log:
[ruby/json] Test and restore behavior around to_json changing depth

When serializing an Array, and one of the elements of the Array requires
calling `to_json`, if the depth is changed, it will be used for the next
entries, which wasn't the case before
https://github.com/ruby/json/commit/5abd43490714, and is not the case with
TruffleRuby and JRuby.

Additionally, with TruffleRuby and JRuby the state's depth after the
`to_json` call is used to close the Array, which isn't the case with
CRuby.
