update fog to 1.36 to fix missing net-ssh error

using the correct Gemfile, but installing at different times to the book,
resulted in different version of numerous items in the Gemfile.lock

those version differences meant that On git push heroku master the following
deployment error occurred:

remote:        Could not detect rake tasks
remote:        ensure you can run `$ bundle exec rake -P` against your app with
no environment variables present
remote:        and using the production group of your Gemfile.
remote:        rake aborted!
remote:        LoadError: cannot load such file -- net/ssh
remote:
/tmp/build_e9fe78a314ac8fb6d1bd3fd9b48ae6af/vendor/bundle/ruby/2.2.0/gems/activesupport-4.2.1/lib/active_support/dependencies.rb:274:in `require'

fog/fog#3765

noted net-ssh was removed because of compatability errors, and is fixed in
fog 1.36.0
