Draft: Update pipeline header

What does this MR do and why?

This MR updates the pipeline header so it does not show the commit name as prominently a before, to only use the pipeline name (from workflow:name) in the heading.

• Add the pipeline id to the page peading
• Removes the commit title from the heading (so only the pipeline name is ever shown)
• Moves the commit information to a line title "For commit sha 📋 My commit title"
• Changes the ref information to use In branchname instead of For branchname to avoid repeating the article For
