Fixes #15136: Search includes fields from other cultures (#15148)

* Fixes #15136: Search includes fields from other cultures

Regex was updated to support block list fields
Unpublished nodes on the supplied culture are not filtered out

* Making the code non-breaking

* Fixed failing publish content query integration tests

The tests were not setting the content as publish in the specifed culture
causing the content items to be ignored
