(aws-lambda-nodejs): Windows bundling issue with chain command

[smivanhamrah]

Describe the bug

We are not able to bundle the lambdas using aws-cdk. we get Illegal character '"' in input file. error.
Windows CMD doesn't not support "&&" as chain command, and instead we should use ";"

// packages/aws-cdk-lib/aws-lambda-nodejs/lib/bundling.ts

function chain(commands: string[]): string {
  return commands.filter(c => !!c).join(' && ');
}

we need to change this function to

// packages/aws-cdk-lib/aws-lambda-nodejs/lib/bundling.ts
function chain(commands: string[]): string {
  const sign = this.osPlatform === 'win32' ? ';' : '&&';
  return commands.filter(c => !!c).join(` ${sign} `);
}

Expected Behavior

yarn cdk deploy .. should be able to bundle the lambdas on windows

Current Behavior

yarn cdk deploy .. raises Illegal character '"' in input file. error on windows.

Reproduction Steps

Try to run following sample on windows

const stack = cdk.Stack()
new lambdaNodeJs.NodejsFunction(stack, 'id', ...)

and then try to bundle the stack

yarn cdk synth
