Subject: [PATCH] TransformsRequest.php cleanArray function fix. (#36002)

When I send a request which has nested json body fields this function does recursive operation and it throws 'maximum function nested level of 256 reached.'.
Size of my data is less than 256.
If I use foreach loop it does not make recursive operation.

My request:
{"sample1":"sample","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[{"title":"aa","children":[]}]}]}]}]}]}]}]}]}]}]}]}]}]}]}]}]}]}]}]}]}]}]}]}]}],"sample2":[{"sample3":"sample","name":"sample"}]}
