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

### 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 ";"
```ts
// 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
```ts
// 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
```

Open packages/aws-cdk-lib/aws-lambda-nodejs/lib/bundling.ts and inspect the chain function and how the bundling platform is selected. Run the reported yarn cdk synth reproduction on Windows, then verify that bundling succeeds there while non-Windows command chaining remains unchanged.
