Issue details

Consider simplifying deploying lambda function code with dependencies as this is non-trivial for beginners.

An existing solution in this space is the lambda-builders library. It has CLI with a JSON-RPC interface. Scope of this library: “given a folder containing function's source code, the selected build action, and path to an artifacts folder, this library will produce built artifacts in the artifacts folder.”

Possibly Pulumi could integrate with it directly to provide a component library where you could write:

const testLambda = new aws.lambda.Function("test_lambda", {
    code: new lambda_builders.Nodejs("../path/to/package.json"), // uses lambda-builders 
    name: "lambda_function_name",
    role: iamForLambda.arn,
    handler: "index.test",
    runtime: "nodejs18.x",
 });

One interesting user story: https://levelup.gitconnected.com/my-journey-with-pulumi-and-the-serverless-framework-2b1398ee581a - there might be additional complications for CallbackFunction coming from closure serialization, but even if those were not fully addressed if we could guide users to a reasonable way to refactor CallbackFunctions into normal functions that could be helpful here.
