[#1247] *: Clarify docs about returned errors from apistatus package

Browse source 
`apistatus` package provides types which implement build-in `error`
interface. Add `error of type` pattern when documenting these errors in
order to clarify how these errors should be handled (e.g. `errors.Is` is
not good).
