Convert images on gitlab flow page to Mermaid
Problem to solve
The Technical Writing team has discussed more than once that the https://docs.gitlab.com/ee/topics/gitlab_flow.html page needs serious and significant CTRT work. One of the problems with the page: the outdated images that do not match GitLab tone and style.
This issue is for replacing as many of the items as possible in whatever manner makes the most sense:
- Mermaid diagrams
- Converting the content over to text
- Some other option I might not have thought of yet
