Jean Boussier 8fded5f5d1 [ruby/psych] Fix RestrictedYAMLTree allowing the Symbol class should allow all symbols
Ref: https://github.com/ruby/psych/pull/495

That's how it works for `safe_load`:
```ruby
>> YAML.safe_load(':foo', permitted_classes: [Symbol])
=> :foo
```

So `safe_dump` should mirror that.
