compiler: suggest `.collect()` when `String` is expected and `Iterator` is found

This commit adds a diagnostic suggestion to help users who forget to call `.collect()` when they have an iterator and the function or variable expects a `String`.

The logic checks if the expected type is `std::string::String` and if the found type implements the `Iterator` trait, if so the compiler provides a suggestion to add `.collect()`

Includes also a UI test to verify if the suggestion appears correctly
