What does this do?

Creates a new "UCSC Grid" pattern for the Query Loop block using the existing "Query Loop Card" pattern. This adds a pattern to the blue "Choose" button in the Query Loop block, which currently only includes default WordPress patterns.

This PR also registers a new pattern category, Query Loop (query_loop), which allows us to create additional query patterns in the future and find them in one place. This grid query pattern and the query loop card pattern were added to the new category.
