Title: Remove documentation about standalone git tag

Specify a git source by itself is no longer supported in the latest version of Bundler.

You can no longer specify a git source by itself. Instead,
either use the :git option on a gem, or specify the gems that
bundler should find in the git source by passing a block to
the git method, like:

git 'git://github.com/rails/rails.git' do
gem 'rails'
end
