Feature request: add ability to add examples for lib

[leha-bot]

I don't know how is better to implement, but maybe think that conanfile.py could provides some snippets for examples which could be used as a metainfo for usage

[leha-bot]

Some examples:
Golang: renders readme (https://pkg.go.dev/github.com/gorilla/mux), also uses godoc
Rust: renders readme and has some strict package structure
Js: has info in package.json, renders readme

(N.B.: I did not investigated deeply this topic yet, comments are welcome)

This is already a supported feature of the conan.io/center system, see https://conan.io/center/recipes/mold?version=2.41.0 which renders the available README.md in the recipe folder

[leha-bot]

So, the package maintainers could just put README.md, yes?
