[TECHNICAL-SUPPORT] LPS-43709 Asset Category selector's and Asset Category Admin's search ignores the user's display language

Hi Tamás,

This is a correction for the behaviour of the Asset Category and Asset Vocabulary searches. The search subjects and results for these items are currently the name fields, which are not localized in the users display language.
Contrary to this, the title field is localized, which means that the user can assign translations in multiple languages to it.
With the modification, the user is able to search Categories and Vocabularies in their own language, by searching after title instead of name. This is achieved by modifying the search service of both Asset Category and Asset Vocabulary, and providing Indexers to these entities (AssetCategoryIndexer and AssetVocabularyIndexer, respectively). Hence, the search is turned from DB based to Indexer based.
I created to subtasks for implementing the Indexers:

LPS-44155 Add Indexer for Asset Categories
LPS-44157 Add Indexer for Vocabularies

Best Regards,
István
