Wrong type hint of setBody of Endpoints\Ingest\Pipeline\Put

[franmomu]

Summary of problem or feature request

I was testing with Elastica library and there were some errors because of setBody(string $body). I've check and all the Endpoints extending AbstractEndpoint overriding setBody don't have this type hint, but the Put one. Should this be reverted or is it on purpose?

I encountered the same problem by calling some thing like this:

$pipline = [
    'id' => 'my_pipline',
    'body' => [...]
];
  
$es->ingest()->putPipeline($pipline); 

The error is:

Argument 1 passed to Elasticsearch\Endpoints\Ingest\Pipeline\Put::setBody() must be of the type string, array given, called in .../vendor/elasticsearch/elasticsearch/src/Elasticsearch/Namespaces/IngestNamespace.php on line 94

Resolved by removing type hint "string" from this line
