The old version of IAR toolchain (8.50.6) has been detected automatically in Qt Creator, but the new version (9.20.4) was not.
Test environment:
- Windows 11
 - Qt Creator 8.0.1 or Qt Creator 9.0.0-beta1
 - IAR Embedded Workbench for Arm 9.20.4
 
I saw the registry info of the new IAR toolchain changed. It seems to affect the toolchain detection.
