Thank you so much for your willingness to contribute! I very much appreciate the effort.
Steps 3-6 are not currently being handled by CI, it is something that we are doing manually on an as-needed basis.
Next steps for you would be to submit the PR to liquibase (against the 3.8.x branch) and mark it as a documentation fix. I will then make sure it gets moved though the system.
When I generate the documentation I will create a PR against the staging branch, where the results can then be previewed (there is a CI solution set up right now that publishes to http://staging.liquibase.org/) and then I typically merge from staging to master after a day or so, sometimes sooner. There is an automatic process at github to publish any changes pushed to master.
For changes in non-generated documentation, please make a PR that targets the staging branch of the liquibase.github.com repository. I have been reviewing and approving and merging those as they come in.
