using components still recommends cpp_info.name

from https://github.com/conan-io/conan-center-index/pull/9409#discussion_r810590913

```
def package_info(self):
self.cpp_info.name = "OpenSSL"
```

the page https://docs.conan.io/en/latest/creating_packages/package_information.html#using-components recommends using `cpp_info.name` (even not `names`!), which was outdated a long time ago.
I think it should be updated to use `set_properties` instead.
