Default, recommended config issues a warning

Problem Description

I expect that Elasticsearch defaults don't produce warnings.

However, I get the following warning:

gateway.auto_import_dangling_indices is disabled, dangling indices will not be automatically detected or imported and must be managed manually

Weirdly, the docs recommend not enabling auto_import_dangling_indices (which is indeed the default).

And yet Elasticsearch itself issues a warning when it's not enabled.

So there seems to be some confusion around I can run Elasticsearch in a safe and recommended way.

Steps to Reproduce

Start elasticsearch.

Logs (if relevant)

{"type": "server", "timestamp": "2022-02-05T18:17:46,465Z", "level": "WARN", "component": "o.e.g.DanglingIndicesState", "cluster.name": "elasticsearch", "node.name": "rivet6", "message": "gateway.auto_import_dangling_indices is disabled, dangling indices will not be automatically detected or imported and must be managed manually" }

This is the bug that #65309 addresses, you should upgrade to pick up the fix.
