Add Ryan Yates to author taxonomy database (#222)

## What this changes

This was missed as part of 
- #53

## Why

I think this is needed if using the Frontmatter VsCode Ext for
autopopulation (I still am not using this extension)

## Type of change

- [ ] Bug fix (non-breaking change that corrects incorrect behavior)
- [ ] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that changes existing behavior)
- [x] Chore / refactor / documentation (no behavior change)

## Checklist

- [ ] Pester tests added or updated to cover the change
- [ ] `Invoke-psake Analyze` passes locally with no new warnings
- [ ] `Invoke-psake Test` passes locally on at least one platform
- [ ] `CHANGELOG.md` updated (required for any user-facing change)
- [ ] Documentation updated if behavior changed

## Additional notes

<!-- Anything reviewers should know: edge cases, known limitations,
follow-up work, testing instructions. -->
