Fix range computation in SolidStateDetectorElement ATLITKSW-125
This MR fixes the computation of the range of a SolidStateDetectorElement, fixing an issue noticed with the ITk strip endcaps (ATLITKSW-125).
A radial shift in the reference frame was improperly applied along the phi direction instead of the radial one.
No impact is observed on default track reconstruction in RunUpgradeTests.py as expected.
