[CodeQuality] Add rule to instantly return nulable value, instead of jumping around it

[TomasVotruba]

 /** @var Property|null $property */
-$property = $this->underscoreCamelCasePropertyRenamer->rename($propertyRename);
+return $this->underscoreCamelCasePropertyRenamer->rename($propertyRename);
-if (! $property instanceof Property) {
-    return null;
-}
-
-return $node;

The example above should return $property in last as we return directly nullable $this->underscoreCamelCasePropertyRenamer->rename($propertyRename) as $property variable.
