Update documentation to account for MutableSettings (#7867)

## Summary of changes

- Fix broken `master` due to concurrent merges of conflicting 

## Reason for change

#7698 moved to defining references in yaml, and in #7723, some of those
references moved, which broke the build

## Implementation details

Update the YAML file and rebuild

## Test coverage

If it builds, we're good!
