C++ string::operator>> broken / missing

# Documentation style bug

## Summary
In the `non-member functions` we cannot open the `operator>>`

## Actual style
It redirects to this page, which is empty / broken :
https://devdocs.io/cpp/string/basic_string/operator_ltltgtgt

## Expected style
Expected to have access to an equivalent of that : https://cplusplus.com/reference/string/string/operator%3E%3E/
