fix(ec2-alpha): imports of SubnetReference and VPCReference from aws-cdk-lib/aws-ec2

[m4rw3r]

Reason for this change

When attempting to use @aws-cdk/aws-ec2-alpha I get the following import error:

node_modules/.pnpm/@[email protected][email protected][email protected][email protected]/node_modules/@aws-cdk/aws-ec2-alpha/lib/subnet-v2.d.ts:5:33 -
  error TS2307: Cannot find module 'aws-cdk-lib/aws-ec2/lib/ec2.generated' or its corresponding type declarations.

5 import { SubnetReference } from 'aws-cdk-lib/aws-ec2/lib/ec2.generated';

I'm using pnpm as the package manager, and typescript is using bundler as the moduleResolution. Following the typescript module resolution output from tsc --traceResolution it seems like ./aws-ec2/lib/ec2.generated is not exposed publicly in the package.json, and it will not attempt to load the file directly since it is a module-import and not a local import.

From what I can tell it was introduced by #35032

Description of changes

This PR changes the imports of SubnetReference and VPCReference to use the publicly available symbols from aws-cdk-lib/aws-ec2 instead of importing them directly from the file itself. The alternative would be to add ./aws-ec2/lib/ec2.generated to aws-cdk-lib's package.json exports.

Description of how you validated changes

Manual update of the relevant .d.ts-files in a project importing @aws-cdk/aws-ec2-alpha will solve the issue.
