What did you do (e.g., steps to reproduce)
Attempting to use the github-pages gem using the docker image with the instructions from the README does not work out-of-the-box, for example:
git clone https://github.com/github/pages-gem
cd pages-gem
git checkout v228
docker build -t gh-pages .
cd ..
git clone https://github.com/github/personal-website
cd personal-website
docker run --rm -it -p 4000:4000 -v ${PWD}:/src/site gh-pagesWhat did you expect to happen?
To be able to run the site locally at localhost:4000
What happened instead?
I got the following error:

The only way I could get it working was by running bundle install before jekyll serve:
docker run --rm -it \
-p 4000:4000 \
-v ${PWD}:/src/site \
gh-pages \
sh -c "bundle install && jekyll serve -H 0.0.0.0 -P 4000"Shouldn't the github-pages gem be already preinstalled in the docker image?
