[Issue] Improve JS Translation DataProviderTest

This issue is automatically created based on existing pull request: #32689: Improve JS Translation DataProviderTest

Description (*)

Currently, DataProviderTest checks that the entire dictionary matches only its translations. When third party extensions are installed that have translation files, this test may fail.

This fix ensures that it is only testing the task it is performing.
