Avoid Kernel.suppress(Exception)

ref: rubocop/rubocop-rails#1547

Using `Kernel.suppress(Exception) { ?? }` is effectively equivalent to:

```ruby
begin
  ??
rescue Exception
end
```

Since rescuing `Exception` directly is discouraged by `Lint/RescueException`,
it makes sense to discourage this usage as well.
