docs: Serialize a dict into a JSON formatted string.
  
          This function enforces rules like the separator and order of keys.
          This ensures that all dicts are serialized in the same way.
  
          This is specially important for hashing data. We need to make sure that
          everyone serializes their data in the same way so that we do not have
          hash mismatches for the same structure due to serialization
          differences.
  
          Args:
              data (dict): dict to serialize
  
          Returns:
              str: JSON formatted string
