[CodingStyle] Skip EncapsedStringsToSprintfRector on heredoc

[samsonasik]

Given the following code:

final class SkipInHeredoc
{
    public function run(string $data)
    {
        $data = 'test';
        $value = <<<CODE
                            Some {$data}
CODE;

        echo $value;
    }
}

In currently produce:

     public function run(string $data)
     {
         $data = 'test';
-        $value = <<<CODE
-                            Some {$data}
-CODE;
+        $value = sprintf('                            Some %s', $data);

which I think should be skipped.
