Checks whether a `find` or `rfind` result is compared with 0 and suggests replacing with `starts_with` when the method exists in the class. Notably, this will work with `std::string` and `std::string_view`.

    std::string s = "...";
    if (s.find("prefix") == 0) { /* do something */ }
    if (s.rfind("prefix", 0) == 0) { /* do something */ }

becomes

    std::string s = "...";
    if (s.starts_with("prefix")) { /* do something */ }
    if (s.starts_with("prefix")) { /* do something */ }
