Summary

After updating from damienharper/auditor:3.3.2 to 3.3.3 and damienharper/auditor-bundle:6.2.0 to 6.2.1 command doctrine:schema:validate started to warn that I need to update schema:

 [ERROR] The database schema is not in sync with the current mapping file.                                              
                                                                                                                        

 // N schema diff(s) detected:                                                                                          

     ALTER TABLE audit_%table% ALTER diffs TYPE JSON;

Expected behavior

Current column type is JSONB, why it wants to change it to JSON?
