[BUG] Handle emrs exception as 400

[noCharger]

What is the bug?

https://github.com/opensearch-project/sql/blob/main/spark/src/main/java/org/opensearch/sql/spark/client/EmrServerlessClientImpl.java#L62-L74

All exceptions are cast to RuntimeException and if not handled properly it will pops up to the top layer

https://github.com/opensearch-project/sql/blob/main/spark/src/main/java/org/opensearch/sql/spark/rest/RestAsyncQueryManagementAction.java#L180-L200

{ "status": 500, "error": { "type": "RuntimeException", "reason": "There was internal problem at backend", "details": "Internal Server Error." } }

How can one reproduce the bug?

create index xxx
on xxx.xxx.xxx (clientip, year) 
WITH (
auto_refresh=true, 
checkpoint_location = 'xxx'
)'

What is the expected behavior?

com.amazonaws.services.emrserverless.model.ValidationException: Unmatched quote at index 2083 (Service: AWSEMRServerless; Status Code: 400; Error Code: ValidationException; Request ID: xxx; Proxy: null)

This should be a 400 instead of 500
