Create samples more real world use-cases oriented

[dlion]

Issue created for tracking purposes

During our retro we identified that lots of samples don't address real use-cases and need to be updated.

As an improvement we can spend some team effort to review these samples and come out with more useful ones.

The samples here are intended to introduce people to the ideas behind buildpacks. Would it be a good idea to direct readers to the paketo and heroku produciton buildpacks for real-world examples? Or maybe to libcnb?

I remember that this issue originated from a conversation with @natalieparellano regarding the fact that lots of our examples were out-to-date and did not address complex use cases.
Yeah maybe directing users to more complex and production-ready paketo/heroku real-world examples would help them to understand better how to do things beyond the basics.
