WIP: Adding new comparison table to new devops comparison page

Why is this change being made?

Adding a new version of the Comparison Page between Gitlab and other tools. I've changed the previous version into a "v1" folder (/source/devops_tools/v1) and kept it's original files unchanged under layout and templates, but then I needed to create a new template and layout (keeping the same name standard, and just adding the "v2" suffix).

Also I assumed there would be a new data/feature.yaml file to support this table, as the existing one does not provide all the info needed, so I also created a "_v2" and added some extra data as an example.

To test, please go to the following URL: http://[your.local.ip]:4567/devops-tools/github-vs-gitlab.html
