Unable to do deployment through Windows with WSL

[hugumoraes]

When trying to deploy a NextjsDistribution to AWS through a Windows environment, some commands doesn't from WSL doesn't work properly because of paths or syntax.
That happens when bundling the ImageOptimizationLambda and when building NextjsBuild.

Expected Behavior

Run cdk deploy, bundle and deploy the NextjsDistribution.

[Warning at /DEV-Web-Admin-MAIN/<Stack_Name>-Web-Admin-Distribution-DEV/DefaultOriginRequestEdgeFn/Fn] AWS Lambda has changed their authorization strategy, which may cause client invocations using the 'Qualifier' parameter of the lambda function to fail with Access Denied errors.
If you are using a lambda Version or Alias, make sure to call 'grantInvoke' or 'addPermission' on the Version or Alias, not the underlying Function

Current Behavior

Whenever bundling with Windows and WSL, deployment will throw an error with the .zip compression on NextjsBuild.ts at line 259 because paths syntax is different.
Then, fixing it, ImageOptimizationLambda.ts will fail at line 80 because cp is not recognize as a valid command (it is copy at windows environment)

Steps to Reproduce

1. Create a stack with all necessary constructs: Bucket, NextjsBuild, NextjsLayer, NextJsLambda, ImageOptimizationLambda and NextjsDistribution.

Context (Environment)

I am trying to do test deployments on my machine before creating a CI/CD to handle the deployment on AWS side, I was able to do the testing by manually changing those lines in node_modules, but would be cool to support it natively from the library.

Would you be open to fixing them and submitting a PR?
Or it may be better to swap out NextBuild for https://open-next.js.org/

Sure, I'll have it in a couple days and submit for review.
