Multi-Branch Workflows example broken

[falstaff1288]

Describe the bug

The multi-branch workflows example is broken as it depends on this repo (https://github.com/concourse/examples) to have at least one branch named feature/<name>.

I currently only see two branches in this repo named main & ``training`

Reproduction steps

1. Try to implement the pipelines from https://concourse-ci.org/docs/how-to/git-guides/multi-branch/

Expected behavior

The branch variable should find feature/* branches.

Updating that guide now. Thanks for reporting about the issue. It had been on my mind to update it since I had a feeling it was a bit stale.
