Set Assembly version in Nuget package

### Describe the feature

The version of Amazon.CDK.Lib.dll in its Nuget package is 1.0.0.0 for the latest version, and every other version that I have checked. Typically the version of the dll matches the version of package.

### Use Case

Keeping the version the same across multiple versions makes the information useless. The version could be displayed in logs. Also, one should be able to interrogate the assembly from code and take action based upon the version. Perhaps it dictates the version of the cdk cli that is used.

### Proposed Solution

### Environment details (OS name and version, etc.)

Windows 10

The issue concerns the Amazon.CDK.Lib.dll assembly inside the NuGet package and reports version 1.0.0.0 while using CDK 2.184.1. Start by tracing how jsii produces and packages the .NET assembly, then compare the assembly metadata with the package version. Done means the DLL version reflects the corresponding package version and remains verifiable from code.
