A string representation of the validation error.
Whether or not documentation URLs are included in the repr is controlled by the
environment variable `PYDANTIC_ERRORS_INCLUDE_URL` being set to `1` or
`true`; by default, URLs are shown.
Due to implementation details, this environment variable can only be set once,
before the first validation error is created.
