Add basic Polka demo

...Had to 🙈

Can bounce this in favor of something less trivial if you'd prefer. The Go TODO app could be good?

Ideally we can use it to introduce another style of app or a new concept, so we don't just have like 10 versions of the same thing haha :D, I can't think of anything at the moment

[lukeed]

Yeah, only came to mind as I was creating PR.

I can do something that attaches to the firebase-admin, incorporating some kind of authorized-access for a specific resource? Would touch on/close #12?

[lukeed]

If you needed more pro examples, I could make it leverage environment variables, but typically you just load a JSON file & ignore it in version control... which is simpler but doesn't require pro.

[tj]

Uncommitted json doesn't really scale to a team either :D and lack of encryption, but anyway hmm yeah maybe utilizing one of the serverless databases would be cool, we don't have any of that yet, not even a dynamo example
