(Contrib) PDO Connection Tracker stopped providing correct attributes for a given PDO

[cedricziel]

I dont have a strong idea what happened except that my app was upgraded to PHP 8.4.

Steps to reproduce
Describe exactly how to reproduce the error. Include a code sample if applicable.

What is the expected behavior?

PDO interactions with a database should be tracked as spans and the connection parameters should be mapped to span attributes (db.system, db.*, ..)

What is the actual behavior?

Only the statement is captured

Additional context
Add any other context about the problem here.

The tests still pass against php 8.4.1 (most tests at least check that the db.system trace attribute is in the span attributes).
