WordPress/wp-includes/blocks/query-pagination-previous.php
gziolo c3ea09ebb8 Editor: Update WordPress packages published for Gutenberg 10.6
It contains several changes in addition to regular update to WordPress packages:
- All newly exposed blocks are now registered on the server.
- Dutone block support was added.
- Border block support was updated.
- New shared function `construct_wp_query_args` was added for the family of Query blocks - it might need some further work.

Props youknowriad.
See #52991.
