FakeHttp json methods unable to create resource for request body #16

Package version: 1.1.1.
PHP version: 8.1.

An attempt to use postJson(), putJson() of FakeHttp class instance:

$this->fakeHttp()->postJson('/', ['key' => 'value']);

Causing error:

Laminas\Diactoros\Exception\RuntimeException : Invalid stream reference provided
/Path/vendor/laminas/laminas-diactoros/src/Stream.php:344

That's because here https://github.com/spiral/testing/blob/master/src/Http/FakeHttp.php#L255 a new Laminas\Diactoros\Stream instance is creating using JSON encoded string as a $stream argument.

According Laminas\Diactoros\Stream::setStream method implementation $stream variable (which contain JSON encoded string) will be used as a file path for fopen().

A quick workaround for this issue will be to use data://text/plain, notation before JSON encoded string which will open a stream using fopen(). More here https://evertpot.com/222/
