/**
 * Workaround to make sure query pagination labels are translated.
 *
 * This function hooks `render_block_context` to transport the `core/query-pagination` block
 * context inside the 'ensemble/pagination' pattern so that the `core/query-pagination-previous`
 * & the `core/query-pagination-next` blocks can use it.
 *
 * @since 1.0.0
 *
 * @param array         $context      Default context.
 * @param array         $parsed_block Block being rendered, filtered by `render_block_data`.
 * @param WP_Block|null $parent_block If this is a nested block, a reference to the parent block.
 * @return string The customized post content's more link.
