(aws-lambda-nodejs): allow comments in tsconfig.json

### What is the problem?

tsconfig.json can have comments in it, as explained here: https://www.typescriptlang.org/docs/handbook/release-notes/typescript-1-8.html#allow-comments-in-tsconfigjson

But the aws-lambda-nodejs will try to load tsconfig and it fails because of comments.

### Reproduction Steps

construct:
```ts
new lambda.NodejsFunction(this, 'put-records', {
bundling: {
preCompilation: true,
},
});
```

tsconfig.json:
```ts
{
"compilerOptions": {
// some comment
"lib": ["es2019", "es2020.promise", "es2020.bigint", "es2020.string"],
"module": "commonjs",
"target": "es2019",

"strict": true,
"esModuleInterop": true,
"skipLibCheck": true,
"forceConsistentCasingInFileNames": true
}
}
```

### What did you expect to happen?

The function to be compiled.

### What actually happened?

```

Read aws-lambda-nodejs/lib/util.ts, especially extractTsConfig and getTsconfigCompilerOptions, then reproduce the failure with the issue's NodejsFunction and commented tsconfig.json. Done means the same construct accepts comments in tsconfig.json and compiles successfully without the JSON syntax error.
