Move elasticsearch/elasticsearch from require-dev to require in composer.json

[IT-Cru]

Does it not make sense that spatie/elasticsearch-query-builder require elasticsearch/elasticsearch not only as a dev dependencies, because builder class already need client and other stuff from elasticsearch/elasticsearch?

I run into this issue when upgrading from spatie/elasticsearch-query-builder 1.x to 3.x which now relies on Elastic 8.x, but during my composer update it doesn't automatically update related elasticsearch/elasticsearch from 7.x to 8.x as I would expect.

Also php-http/promise should be added as require dependency to composer.json.
