Fix bundler_spec test

[utkarsh2102]

Thanks for your awesome work on maintaining pry, @kyrylo! ❤️

However, whilst maintaining pry in Debian, I noticed that there was a test failure:

➜  pry git:(master) rspec spec/integration/bundler_spec.rb

Randomized with seed 32029
Traceback (most recent call last):
-e:5:in `<main>': uninitialized constant Bundler (NameError)
F

Failures:

  1) Bundler when Pry requires Gemfile, which doesn't specify Pry as a dependency loads auto-completion correctly
     Failure/Error: expect($CHILD_STATUS.exitstatus).to eq(42)
     
       expected: 42
            got: 1
     
       (compared using ==)
     # ./spec/integration/bundler_spec.rb:26:in `block (3 levels) in <top (required)>'

Finished in 0.54534 seconds (files took 0.58163 seconds to load)
1 example, 1 failure

Failed examples:

rspec ./spec/integration/bundler_spec.rb:10 # Bundler when Pry requires Gemfile, which doesn't specify Pry as a dependency loads auto-completion correctly

This PR fixes the same and also arranges those requires in alphabetical order 😄

Thanks for the kind words 🤎 but I probably don't deserve them 😅
