Originally added in Elasticsearch in commit
2c5f1d1569, removed in OpenSearch in
3eac282c57
Note that this just adds support of 'elasticsearch' header, there's no
'opensearch' header support as such.

Renaming caused breakages in API versioning code, so removed that part
because we will anyways be removing the whole Elastic API versioning
logic in near future.
Also removed unused variable in .github/workflows/integration.yml
