Remove "title" GIN index from the item table

The 'title' field was removed from the item schema and so the 'title' index was removed from the DB as seen by this commit: https://github.com/folio-org/mod-inventory-storage/commit/cee193644ed4b60327491664c217dcd60c81f19c#diff-162ca424ba9ad000edded275876b325b

However, the schema.json still has a 'title' GIN index for item as seen here: https://github.com/folio-org/mod-inventory-storage/blob/master/src/main/resources/templates/db_scripts/schema.json#L230

Can this index be removed as well?
