Switch back to `Hash.dup`
The performance difference between `Hash[]` and `Hash.dup` looks to have
been narrowed by @tenderlove via this commit --> https://github.com/ruby/ruby/commit/b3803cc49ad382e23291d75ce57ffb2b74bb9577#diff-eff9999082c8ce7d8ba1fc1d79f439cf.
Since this commit first appeared in Ruby 2.0.0, and since Rails now
requires a minimum Ruby version of 2.2.2, this performance boost should
be available for all users.
