Installation fails on MacOS due to broken .NET dependency

[awelc]

When running the dev_setup.sh script installation of .NET on MacOS (M1) fails with the following error:

dotnet-install: Attempting to download using primary link https://dotnetcli.azureedge.net/dotnet/Sdk/5.0.404/dotnet-sdk-5.0.404-osx-arm64.tar.gz

dotnet_install: Error: Could not find `.NET Core SDK` with version = 5.0.404
dotnet_install: Error: Refer to: https://aka.ms/dotnet-os-lifecycle for information on .NET Core support

It seems like the problem is related to .NET version 6 now being the default one which might have affected what's available for CI installations.

As a quick follow-up, it seems like the dotnet-install.sh script downloaded and used by dev_setup.sh script no longer supports installing any 5.0 versions.

Another quick folllow-up - it looks like if you are on a Mac with the M1 chip you are out of luck as there is no Arm64 binary for the 5.X versions (see here).

@modocache do you have an idea what is happening here? I thought we upgraded to v6 because of M1, but maybe I remember this wrong.

Actually, scratch my last comment, as all should be good with Rosetta emulation (sorry - pretty new to M1 Macs).

In any case, I may have a quick PR to fix this, but I will not file it today - the solution is basically to force downloading of the x64 version (as Arm64 version does not exist), though at this point I am not sure if the additional arch option below has to be predicated on the OS type.
