GAE ruby standard environment w/nokogiri broken after some change from google

[crivotz]

Same as #31 different version of nokogiri

Your bundle is locked to nokogiri (1.18.9-x86_64-linux) from rubygems repository
https://rubygems.org/ or installed locally, but that version can no longer be
found in that source. That means the author of nokogiri (1.18.9-x86_64-linux)
has removed it. You'll need to update your bundle to a version other than
nokogiri (1.18.9-x86_64-linux) that hasn't been removed in order to install.

Same for 1.18.10
