Update RFC references and remove unused TODO comment

Replaced outdated RFC 2616 references with RFC 9110 in the `Error` class to ensure accuracy and compliance with current specifications. Also removed an obsolete TODO comment from the `PlaceAttribute` class since it was no longer relevant. These changes improve documentation clarity and maintainability.
