.NET SDK install flakiness sourcing via installer scripts with internal errors

[martincostello]

The new builds.dotnet.microsoft.com and ci.dot.net domains seem to exhibiting flakiness when attempting to download the latest .NET SDK on multiple operating systems based on errors I'm getting in GitHub Actions workflows in multiple repositories.

Retrying the build will lead to success eventually, but clearly that's not a good experience for consumption.

Windows:
