fix: parse qualified explicit destructor calls

A qualified destructor-id in an explicit destructor call via `->`/`.`, e.g.
`p->std::vector<int>::~vector()` or `p->A::~A()`, produced an ERROR node.
`qualified_identifier` already accepts a trailing `destructor_name`, but
`qualified_field_identifier` (the member-access path) did not; mirror it there.
