Update rack-timeout setter in puma recipe

[rjherrera]

In rack_timeout's 0.5.0 release, legacy setters were removed (zombocom/rack-timeout#125), which made this line not longer functional.

In order to fix it, similar to what is suggested in zombocom/rack-timeout#130, it should be changed to:

config.middleware.insert_before Rack::Runtime, Rack::Timeout, service_timeout: (ENV["RACK_TIMEOUT"] || 10).to_i

Great catch!

What do you think about using the environment variables support already baked into rack-timeout?

I also saw that, and it looks cleaner. It would imply deleting that line, but I'm not sure on how to communicate this, maybe explicitly describing that expected behavior in the README.md?

I know that if we delete the line and the env var is not defined, it would not break, but it feels like hiding something that was explicit before. What do you think?
