As described in title, the script tries to download x64 sdk even though the architecture options is specified

➜  ~ ./dotnet-install.sh -c 10.0 --architecture arm64
dotnet-install: Attempting to download using aka.ms link https://builds.dotnet.microsoft.com/dotnet/Sdk/10.0.100/dotnet-sdk-10.0.100-osx-x64.tar.gz

    [Triage] The script is likely reading the machine architecture and not honoring the --architecture flag. We should investigate whether or not this is the case. It's also possible that the aka.ms links are pointing to the incorrect artifacts.

    @DosangGu - what's the architecture of the machine you're running on?

    It's arm64. I ran the script with mac mini (m2 chip).

    I'm unable to repro with Apple M1 (ARM) Mini

    @DosangGu - Can you please provide some more details: What is the output when you run uname -m? Additionally, what is the output when your run the scripts with the --verbose flag?

    It seems my downloaded script is outdated. Using your example script installed arm64 sdk.

    But I'll provide the log which I tried with old script. Seems the old script parsed architecture as arm64 but it tries download x64 sdk.

    ➜  ~ uname -m
arm64
    ➜  ~ ~/dotnet-install.sh -c 10.0 --verbose
dotnet-install: Note that the intended use of this script is for Continuous Integration (CI) scenarios, where:
dotnet-install: - The SDK needs to be installed without user interaction and without admin rights.
dotnet-install: - The SDK installation doesn't need to persist across multiple CI runs.
dotnet-install: To set up a development environment or to run apps, use installers rather than this script. Visit https://dotnet.microsoft.com/download to get the installer.

    Looks like this was fixed in #526. As you said, using a newer version of the script will resolve the issue.
