refactor: Remove const to fix performance-move-const-arg clang-tidy errors

The warnings look like:

src/rpc/util.h:192:19: error: std::move of the const variable 'name' has no effect; remove std::move() or make the variable non-const [performance-move-const-arg,-warnings-as-errors]
        : m_names{std::move(name)},
                  ^~~~~~~~~~    ~
