Port Actors Quickstart to more languages: Go, Java, Python, JavaScript

[paulyuk]

The idea would be to port what we did for .NET here: https://github.com/dapr/quickstarts/tree/master/actors/csharp/sdk

Any single language as a PR is welcome.

It helps to look at the examples folders of each SDK to get inspiration how to work with the SDK, e.g.
https://github.com/dapr/go-sdk/tree/main/examples/actor

I'm quite happy to assist.

Removing assigns, so this is now open again.
