Avoiding deleting SLM history indices in rest test case cleanup

[masseyke]

If an SLM policy happens to run during a rest test, an slm history index will be created, which then causes a failure during test cleanup like:

org.elasticsearch.smoketest.DocsClientYamlTestSuiteIT > test {yaml=reference/query-dsl/simple-query-string-query/line_291} FAILED
    org.elasticsearch.client.ResponseException: method [DELETE], host [http://127.0.0.1:43027], URI [*,-.ds-ilm-history-*?expand_wildcards=open%2Cclosed%2Chidden], status line [HTTP/1.1 400 Bad Request]
    {"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"index [.ds-.slm-history-5-2023.10.09-000001] is the write index for data stream [.slm-history-5] and cannot be deleted"}],"type":"illegal_argument_exception","reason":"index [.ds-.slm-history-5-2023.10.09-000001] is the write index for data stream [.slm-history-5] and cannot be deleted"},"status":400}

This PR excludes the SLM history index from deletion the same way we exclude the ILM history index.

Closes #100536
