Add bundle install to image build
When building docs-latest
Docker image, if a Ruby dependency is updated (!2275 (merged)) but a dependent Docker image isn't updated to use the new dependencies, build errors can occur: https://gitlab.com/gitlab-org/gitlab-docs/-/jobs/1808429726.
This MR adds bundle install
to the process to pick up any uninstalled Ruby dependencies, and basically matches the yarn install
there for Node.js dependencies.
