[Feature Request] Add sample for usage with Pino-logger

[mjameswh]

Describe the solution you'd like

We already have a sample for using the SDK with an upstream Winston logger (custom-logger), and in most cases, writing custom log adaptors is simple enough. Yet, we get a few requests specifically regarding usage with the Pino logging framework, and notably regarding how to also get Pino-style loggers in activity and workflow code (here's one such request).
