Stored benchmarks schema

Stored schema on the benchmarks file is modelrater-benchmarks/1. Both public copies store that schema. The file stores one schema, so the bar is full. The bar is the stored label, not a score. The catalog schema is modelrater-repo/3. The slice schema is modelrater-or-slices/1. The digest schema is modelrater-analysis-digest/1. The popular schema is modelrater-popular-telemetry/1. The leaderboard schema is modelrater-leaderboard/3. Those are different strings. A missing schema stays off the page.
