cdk init: rename "dotnet" to "csharp"

[eladb]

Because it's a C# project

@eladb Can I work on this ? it seems only this below directory needs to be changed for this https://github.com/awslabs/aws-cdk/tree/master/packages/aws-cdk/lib/init-templates/app/dotnet to https://github.com/awslabs/aws-cdk/tree/master/packages/aws-cdk/lib/init-templates/app/csharp and the corresponding change should be updated in the documentation for language argument of command line params . Please let me know if my understanding is correct .
I think below line looks for the existing template languages based on the directory name
https://github.com/awslabs/aws-cdk/blob/master/packages/aws-cdk/bin/cdk.ts#L38

Thanks so much for proposing. And you are correct in your approach. Technically this is all that needs to be changed in the CDK repo, but we have a bunch of integration tests for "cdk init" in another repo that also must be updated.

Perhaps what we can do is copy & paste the "dotnet" directory into "csharp" so the change will be backwards compatible and then we can update our integration tests and deprecate "dotnet".

@eladb that would be a good idea. I Can start making the changes in my branch if it's fine with you. Can you provide the integration test repo url so that I can update them?

[eladb]

Go ahead, much appreciated

[Niladri24dutta]

@eladb Can you please let me know the location for the integration tests ?

[eladb]

Our integration tests are mastered in a private repo. Let's just start with duplicating "dotnet" to "csharp" and we'll take it from there.

@eladb got it ... I will create the PR for this
