what examples are shown in the docs

The sockshop module is great, cause it's fairly complex, but we also need something very basic. Right now we have a hypothetical errors.io app, we should either make it somewhat real, or provide a simple alternative to sockshop module (cause there are two many things in there).

New examples should include most of macros we have now. Perhaps updating the examples/modules/sockshop would be a good start, it'd be good to just start using kubegen in sockshop repo too.
