[DRE-maint] Bug#924230: jekyll: Could not load bundler

[Bidon]

Package: jekyll
Version: 3.8.3+dfsg-3.1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

On Debian buster/sid.
Creating a fresh site gives me a warning related to bundler.

$ jekyll new mysite
Could not load Bundler. Bundle install skipped.
New jekyll site installed in /home/username/mysite.

The site seems to be created as the directory and the main files of the site
are present but I can't run a local server.

$ cd mysite
$ jekyll serve
Traceback (most recent call last):
        3: from /usr/bin/jekyll:9:in `<main>'
        2: from /usr/lib/ruby/vendor_ruby/jekyll/plugin_manager.rb:48:in
`require_from_bundler'
        1: from /usr/lib/ruby/2.5.0/rubygems/core_ext/kernel_require.rb:59:in
`require'
/usr/lib/ruby/2.5.0/rubygems/core_ext/kernel_require.rb:59:in `require': cannot
load such file -- bundler (LoadError)

Maybe bundler is missing?
