Update how-to/testing-database.md + general prompt

In this document it added language codes to urls starting with "https://sqlmodel.tiangolo.com/", resulting in broken links.

So I changed the instructions in the translate.py, so that it only adds the language code when the URL starts exactly with "https://fastapi.tiangolo.com".
