Update dependencies
Update dependencies

When I execute `bundle install`, it shows the following error:

Bundler could not find compatible versions for gem "rouge":
  In snapshot (Gemfile.lock):
    rouge (= 3.23.0)

  In Gemfile:
    github-pages (= 212) was resolved to 212, which depends on
      rouge (= 3.26.0)

    jekyll was resolved to 3.9.0, which depends on
      rouge (>= 1.7, < 4)

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.

So I use it recommendation to execute `bundle update` to update
dependencies of jekyll to fix this error.
