Disable Naming/BlockForwarding cop as it breaks Sorbet

- I'm sure there is a solution somewhere, but I couldn't find one.
- Basically Sorbet runtime complains about missing params in sigs, since
  `&block` turns to `&` with the autocorrections for this cop and that's
  not defineable in the `params` part of the Sorbet signature?
