Unclear documentation for Advanced Search Backend (Elasticsearch/Opensearch/AWS)

Problem to solve

Unclear documentation about permissions required for using Opensearch or Elasticsearch

It is unclear which permission should be used for which product (Elasticsearch/Opensearch/AWS) in https://gitlab.com/gitlab-org/gitlab/-/blob/master/doc/integration/advanced_search/elasticsearch.md#permissions-for-fine-grained-access-control

Proposal
