Add example how to redirect traffic from one port to another.

That is probably fine (maybe fix style), but instead of adding examples in the README maybe it worth adding examples in the examples directory? This allows to have acceptance tests where we exercise the examples code to ensure it applies correctly as a catalog, ensuring that these examples are still valid if the API happen to be changed:

Re the examples I'll have a look next time ... else leave this here for a month or so and I'll have a go.
These examples will be a bit weird in that you need a lot of extra puppet code to actually disable nftables from really doing what it does since that is doomed to work in docker and the github runners. All it really does a nft syntax chcek but that is still very useful.
