Lambda Ruby Runtime doesn't Support ZipFile

[skorfmann]

This implies that the Lambda Ruby runtime supports ZipFile (aka inline code).

aws-cdk/packages/@aws-cdk/aws-lambda/lib/runtime.ts

Line 50 in a1cd743

public static readonly RUBY_2_5 = new Runtime('ruby2.5', RuntimeFamily.RUBY, { supportsInlineCode: true });

However, when deploying a function like this

new lambda.Function(stack, 'foobar', {
  code: new lambda.InlineCode('def handler(event:, context:) ; "success" ; end'),
  handler: 'index.handler',
  timeout: cdk.Duration.seconds(15),
  runtime: lambda.Runtime.RUBY_2_5
});

I get the following error from CloudFormation

 19/52 | 9:14:58 PM | CREATE_FAILED        | AWS::Lambda::Function            | foobar (foobarF27D68A9) ZipFile can only be used when Runtime is set to either of nodejs8.10, nodejs10.x, nodejs12.x, python2.7, python3.6, python3.7.

The docs are also mentioning just nodejs and python

Environment

• CLI Version 1.22.0 (build 309ac1b)

Ack, supports inlineCode needs to be unset for Ruby.
