Use relevant examples instead of the inventors

This sample is a bit silly: https://github.com/questdb/go-questdb-client/blob/2190485745fb270465fabf6af364bcb7dee3b61a/examples/from-conf/main.go

I assume this was taken from Java samples which I am guilty of using in the past.

We should use samples related to QuestDB use-cases. Ideally the same samples across clients. Since the samples are imported into Cloud and shown in a console.
