Invalid argument exception with OpenSearch Serverless

[CermakM]

Describe the bug
When using the plugin in Goland with AWS OpenSearch Serverless, while the connection is working, I get the following error from the inspection:

org.elasticsearch4idea.ey: GET <opensearch endpoint>/_cat/indices/*?format=json&expand_wildcards=open 400 {"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"request [/_cat/indices/*] contains unrecognized parameter: [expand_wildcards]"}],"type":"illegal_argument_exception","reason":"request [/_cat/indices/*] contains unrecognized parameter: [expand_wildcards]"},"status":400}

This makes it impossible to use the plugin, since I can't even execute es request.

Steps to reproduce
Install the Plugin and connect to an OpenSearch Serverless endpoint.

Expected behavior
No error occurs.

Environment information:

• OS: MacOS
• plugin version: 2024.1.3
• Elasticsearch or OpenSearch version: 2.0.2
