[Bug]: Intl.getCanonicalLocales tests fail on Windows Server 2022 due to mismatch ICU version

[QuellaZhang]

ChakraCore Version

97e68c9

Steps to reproduce

• git clone https://github.com/microsoft/ChakraCore C:\gitP\microsoft\ChakraCore
• cd /d C:\gitP\microsoft\ChakraCore
• msbuild /m /p:Platform=x64 /p:Configuration=Test /p:WindowsTargetPlatformVersion=10.0.22621.0 Build\Chakra.Core.sln /t:Rebuild
• cd /d C:\gitP\microsoft\ChakraCore\test
• cmd.exe /c ver
• python runtests.py -t --x64

Proof of concept

if (WScript.Platform.ICU_VERSION < 62) {
...
} else {
...
}

Exception or Error

Additional Context

We build Chakra using the latest MSVC to detect compiler regressions. After updating the SHA to 97e68c9, we observed that Chakra test exhibited different behaviors on CI test VMs compared to local test VMs. The root cause was conclusively identified as differences in the Windows and ICU versions.

Environment:
CI VM:

• OS: Windows Server 2022 (10.0.20348)
• ICU_VERSION: 64
• Intl.getCanonicalLocales Output: "de-DE-u-co-yes-kn-true"
• Chakra test result: 2 tests failed

Local VM:

• OS: Windows 11 (10.0.22631)
• ICU_VERSION: 68
• Intl.getCanonicalLocales Output: "de-DE-u-co-kn"
• Chakra test result: All passed
