Describe the feature you'd like to request

In Gen1, its possible to create functions in various languages:

? Choose the runtime that you want to use: (Use arrow keys)
  .NET 8
  Go
  Java
❯ NodeJS
  Python

We currently only support the NodeJS runtime - we should support all.

Describe the solution you'd like

In Gen2, non JS runtimes are supported via a flavor of the defineFunction API:

export const sayHelloFunctionHandler = defineFunction(
  (scope) =>
    new Function(scope, "say-hello", {
      handler: "index.handler",
      runtime: Runtime.PYTHON_3_9, // or any other python version
      timeout: Duration.seconds(20), //  default is 3 seconds
      code: ...
);

More information here: https://docs.amplify.aws/vue/build-a-backend/functions/custom-functions/.

Implementation Notes

• Since the CDK Function construct exposes the same API regardless of runtime - we expect common logic to support all different languages. If however we see that special handling is needed per language, we should prioritize python and go first.

Describe alternatives you've considered
