Fix method signatures for ReflectionProperty

[derrabus]

Fixes #7357

Sorry, I have no clue how to fix that test. 🙈

@derrabus See eg #7406, there are delta callmaps for each PHP version. If the signature needs to be changed in all of them, update the historical callmap so it matches, if it needs to be changed only for some specific version onward, add the change to that delta.

@derrabus no worries! We have a documentation page dedicated to those changes here: https://psalm.dev/docs/contributing/editing_callmaps/ if you need more informations. But yeah, @AndrolGenhald is right, Callmap.php is the current state of PHP8.1 but we use delta files in order to pinpoint what was the state of every other PHP version until "historical" (which is 7.0), so you need to update those too.

4.x branch is closed now as we prepare for the 5.0 release. Please target the master branch instead.

The original issue seems to be already resolved.
