Readme doesn't mention InformationalVersion or SourceRevisionId #1694

In Source Link included in the .NET SDK we learn the the assembly InformationalVersion attribute now includes the git commit hash thanks to sourcelink.

MSBuild reference for .NET SDK projects#SourceRevisionId also indicates that an MSBuild property is available.

Reading (ha) just the readme would lead one to believe that the only thing sourcelink does is embed some JSON in the PDB.

Could the readme be updated to at least hint about this additional functionality? Is there anything else hidden away somewhere?
