Update Psalm to 4.8.1

BC Break	mostly no

Summary

While we did most of the argument names cleanup in #4172, the updated Psalm flagged some more cases. Since we already support PHP 8, changing argument names could be technically called out as a BC break, I believe this change is acceptable:

1. The argument names are inconsistent across implementations, so the current state cannot be considered correct.
2. All changes are made in the methods that accept a single argument, so it's very unlikely that the calling side passes the argument by name.

The inconsistent naming was also a BC break, so this would fix some issues.
