elasticsearch 8 support

Hello! Thank you for all the hard work, it is very much appreciated.

Is there a matrix that maps elastic version to java-io-elasticsearch version? I noticed [rest client 7.9.2](https://github.com/apache/beam/blob/master/sdks/java/io/elasticsearch/build.gradle)
as I was encountering the error below in trying to perform a simple read from elasticsearch 8.3.5.

URI [/_search/scroll], status line [HTTP/1.1 400 Bad Request]
{"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"Cannot parse scroll id"}],"type":"illegal_argument_exception","reason":"Cannot parse scroll id","caused_by":{"type":"e_o_f_exception","reason":"tried to read: 1668254 bytes but only 0 remaining"}},"status":400}

Your help would be appreciated!
