clean test data

using manual inspection, ensure that all json1 fields contain the information that can be extracted from the PDF.

And automatically check whether they match the schema, see https://towardsdatascience.com/how-to-use-json-schema-to-validate-json-documents-ae9d8d1db344
Validation should only check and not modify the json1 values.
If there is a validation error, either the json1 value or the schema needs to be corrected. It should be carefully decided which one to correct.

2. Validation was added based on the schema. There was no validation error.
