Auto-run nuget acquisition for SQL and KQL

[sharoncxu]

Is your feature request related to a problem? Please describe. Users have to run an acquisition string, e.g. #i "nuget: https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet-experimental/nuget/v3/index.json" #r "nuget: Microsoft.DotNet.Interactive.SqlServer, 1.0.0-beta.22606.2" to use R and SQL

Describe the solution you'd like Autorun the nuget acqusition for the user so they don't have to take an extra step

We need to figure out if we can fix this after the GA release of Jupyter subkernel support.

This is Post-GA work.

This is partially addressed by #3810. I'm going to close it because actually running the NuGet acquisition code on the user's behalf requires a much wider design discussion, but #3810 satisfies the discoverability aspect of the issue.
