Providing command line options -a arm64 or --architecture arm64 downloads wrong editor architecture (x64)

Steps to reproduce:

1.  Open terminal (CMD)
2.  Try downloading any Unity editor using -a arm64 or --architecture arm64 command line options
3.  Example: "C:\Program Files\Unity Hub\Unity Hub.exe" – --headless install --version 6000.3.0f1 --changeset d1870ce95baf -a arm64

Actual results: 
Version is downloaded with x64 architecture not ARM64

Expected results: 
Version is downloaded with ARM64 architecture

Reproducible with versions: 
3.15.3

Tested on (OS): 
Windows 11 ARM 64

Notes:

•  Works as expected on MacBook M1 machines
• https://docs.unity3d.com/hub/manual/HubCLI.html - states these command line options should work
• Providing NO options, the downloader defaults to the correct architecture ARM64
