fix(search): fixes issue where exact match exclusive flag broke quoted structured search

[nmbryant]

Related to this issue: #10505
We found that enabling the flag ELASTICSEARCH_QUERY_EXACT_MATCH_EXCLUSIVE resolved the problem where quoted search with _ or - had no effect. However, enabling this flag broke structured queries tat had quotes (which are needed if the search string contains a space) due to the check that has been removed by this PR.

It seems that this logic isn't intended and was just an artifact of modeling the function getStructuredQuery after the getSimpleQuery function:

datahub/metadata-io/src/main/java/com/linkedin/metadata/search/elasticsearch/query/request/SearchQueryBuilder.java

Line 321 in 3a72d92

executeSimpleQuery = !(isQuoted(sanitizedQuery) && exactMatchConfiguration.isExclusive());
