[chore] Clarify that Unmarshaler only supports structs (#13045) 

<!--Ex. Fixing a bug - Describe the bug and how this fixes the issue.
Ex. Adding a feature - Explain what this achieves.-->
#### Description

Clarifies usage of `confmap.Unmarshaler`. This is a limitation that
currently exists since mapstructure will fail to map between the types.
