Rewrite domain in releases.json

This transformation is the result of a tool.

• It builds a new URL based on a specific scheme.
• Scheme: $"https://builds.dotnet.microsoft.com/dotnet/{component}/{version}/{fileName}"
• It does a HEAD request on each URL.
• If the request returns a 200 status code, JSON url is rewritten.
• A small set of files only exist at download.visualstudio.microsoft.com. I don't know why. I don't think it matters.
• I ran a script (on the updated files) that validates that every url returns 200. That tool errors (stops) if it hits a non-200 case.
