Docs: Git, expand info on complex branching flows
In #519149 (closed), as part of my Q1 stage lead work, I did a repeated series of interviews with a former solutions architect. The result was https://docs.gitlab.com/user/project/repository/branches/strategies/, which stubs out descriptions and Mermaid diagrams for three common branching scenarios that are more complex than our standard.
This issue is to track building out those branching descriptions with as much information as I can get from varying sources this quarter.
