The current version of github pages requires you set use Jekyll 3.8.5 and github-pages 202. When I set this up, I also had to set a specific version for jekyll feed. Here's the relevant lines you need in your Gemfile:

gem "jekyll", "~> 3.8.5"
gem "github-pages","~> 202" , group: :jekyll_plugins
# If you have any plugins, put them here!
group :jekyll_plugins do
  gem "jekyll-feed", "~> 0.11.0"
end

After that, try removing your Gemfile.lock and running bundle install.

I have a repo here with a minimal version set up.
