Multilingual title for Person blocks embeded via layout does not take.

[mariacha]

Describe the bug
When fixing https://github.com/wri/wriflagship/issues/1047 I introduced a bug where the overriding title DOES display on Paragraphs, but that means the label does not display on blocks embeded via layout builder. So the goal here is to revert a9d3e89 and fix the bug with a paragraph preprocessing function instead, which will set the "label" for the field equal to the block's title (based on the current language).

Query to get pages to check:

SELECt * FROM paragraphs_item LEFT JOIN paragraphs_item_field_data USING (id) WHERE paragraphs_item.type='person_listing'

Dev tasks

• Revert a9d3e89
• Fix the bug with a paragraph preprocessing function instead, which will set the "label" for the field equal to the block's title (based on the current language).

This has been fixed on Flagship. Since Flagship is not multilingual, the only thing to test is that Person Listing paragraphs continue to have the correct, unique titles:
