Hi, Schemers.

The specification says it use `temporarily` to simulate the
`parameterize` in Chez. However its given example doesn't get the same
result while running under Chez (with `temporarily` replaced by
`parameterize`)

```
Chez Scheme Version 10.2.0
Copyright 1984-2025 Cisco Systems, Inc.

> (let ([p (make-parameter 1 (lambda (x) (+ x 1)))])
    (parameterize ([p 4]) (values))
    (p))
3
```

The example says[1] it return 5, and the test[2] of SRFI-226 implementation
also expect the example to return 3.

Should we need an errata entry for it?
