Bump elasticsearch version

[tajweb]

I can't run Explorer with ElasticSearch because of version coflicts

 Problem 1
    - Root composer.json requires jeroen-g/explorer ^3.7 -> satisfiable by jeroen-g/explorer[3.7.0].
    - jeroen-g/explorer 3.7.0 requires elasticsearch/elasticsearch ^7.16 -> found elasticsearch/elasticsearch[v7.16.0, ..., 7.x-dev] but it conflicts with your root composer.json require (^8.9).

Your options:

• downgrade the requirement in your root composer
• contribute support for newer ES to this package
