Updated expected output of FastShowerCellBuilderTool_test after !54593 (ATLASSIM-5934)
!54593 (merged) fixed the Tile Tracking Geometry, so it is not unexpected that it would also alter FastCaloSim output.
This merge request updates the expected output of FastShowerCellBuilderTool_test
to match the current output.
Should fix ATLASSIM-5934.
NB Ideally this change should not be swept autmatically to master, but should be added to !54186 (merged) (same as !54593 (merged) but for master) before it is merged.
