bug#61531: 30.0.50; c++-ts-mode: "}" indented wrong

[xhcoding <xhcoding@foxmail.com>]

The closing '};' is indented wrong in the following class/struct definition:

class Person {
    std::string name;
    int age;
    };

The expected indentation:

class Person {
    std::string name;
    int age;
};
