Re-sync dotnet-install.ps1 to remove azureedge.net

[rhysparry]

Background

The azureedge.net domain is no longer used to provide the .NET SDK. This PR synchronises our forked version of the dotnet-install.ps1 script with the upstream version.

Results

• References to azureedge.net have been removed
• The NoCdn parameter of the script has been removed (as per upstream)

How to review this PR

This PR primarily changes the old references to domains that are no longer used to serve the dotnet SDK. This keeps the changes relatively constrained following the most recent synchronisation:

• Update dotnet-install.ps1 script for new CDN urls #1053

To compare with the current version upstream, the following command can be run (tested in bash):

diff --color=auto --strip-trailing-cr <(curl --location https://dot.net/v1/dotnet-install.ps1) dotnet-install.ps1

Pre-requisites
