Summary

Psalm incorrectly reports an InvalidNamedArgument error when using named arguments for new ReflectionClass(objectOrClass: $foo).

Code sample

Reproducible snippet:
https://psalm.dev/r/d3654927ce

Psalm output:

ERROR: InvalidNamedArgument - 3:35 - Parameter $objectOrClass does not exist on function ReflectionClass::__construct

Additional context

• PHPStan has no issues with the same code:
  https://phpstan.org/r/1f537f1a-cc83-4a5e-881d-b54ab8b56141

• PHP itself works fine at runtime, even with named argument objectOrClass:
  https://onlinephp.io/c/a51e4

• Official PHP documentation for ReflectionClass::__construct clearly defines $objectOrClass as the parameter name:
  https://www.php.net/manual/en/class.reflectionclass.php

• Problem in Psalm source:
  It looks like the cause is this stub:
  https://github.com/vimeo/psalm/blob/6.x/stubs/Reflection.phpstub#L20
  where the constructor is defined with a different parameter name or without named argument support.

Expected Behavior

Psalm should allow using objectOrClass as a valid named argument for ReflectionClass::__construct.

Environment

• Psalm version: 6.x
• PHP version: 8.2
• Platform: tested on online playground and local.
