Nuget Upgrade:

Breaking changes to handle internally:

• System.CommandLine had a major API change that required extensive changes to our CommandLine.cs file
• Spectre.Console added WriteAnsi that we need to add to our interfaces
• Spectre.Console changed Style from class to struct (only affected our unit tests)
• Microsoft.Build.Framework changes to resolve to fix new warning MSBL001
