Title: Remove unneeded requires in rake task.

- rspec/core/version require was added in
390392e7e76429bbeddedd615565e858c70194f9 but
looks like it was never actually used.
- We used to have some warnings emitted by the rake
task (and thus needed to load that support) but
don’t have any more warnings.

@postmodern, do you remember why you added `require 'rspec/core/version'` in that commit?
