Symfony version(s) affected

6.3.0

Description

When opening serializer profiler, twig exception about helper variable is thrown. As far as I debugged, #48759 PR by @javiereguiluz might be at fault here as this line: {% import _self as helper %} was removed from template and some but not all occurences of helper were changed to _self.
I can do a PR if all that should be done is changing helper to _self but maybe @javiereguiluz could tell why some helper occurences were left?

How to reproduce

1. Install latest 6.3 dev version
2. Open serializer profiler

Possible Solution

changing helper to _self in twig template
