Resolve "Warning: var_export does not handle circular references"

Problem/Motivation

We're seeing this error on some nodes:

Stack trace : 
Warning: var_export does not handle circular references in Drupal\patternkit\PatternFieldProcessorPluginManager->traverseSchema() (line 229 of /modules/contrib/patternkit/src/PatternFieldProcessorPluginManager.php)

This notice/warning/error occurs when the block data deviates from what the defined pattern schema allows. This is most likely caused by migrated patterns from D7 that do not align with the latest schemas for those patterns provided.

Proposed resolution

We were able to successfully resolve this issue by replacing the 2 var_export() instances with json_encode() here: https://git.drupalcode.org/project/patternkit/-/blob/9.1.0-beta8/src/Pat...
