Unlock Rack gem version

[Wojciech Wnętrzak]

I can see in 591d213 that rack gem version was locked.
There is already 13.x of rack gem which is not allowed by this restriction.
Is there any reason to lock it or can it be relaxed?

Related to #422
I think that this can be closed then. What we would need is a new release.

The commit closing #422 seems to miss the development dependency: 415f283

gem.add_development_dependency 'rake', '~> 12.3'
why is it a development and runtime dependency?

That's very nicely spotted. I have no clue why would it be on both dependencies...

Would like to know as well, why rake is restricted to < 13?
