feat: boolean columns (tests): update config, add inputs and update r…

…esults

- Update {exampleDataset,exampleDatasetAsNdjson}/database_config.yaml.

- `small_metadata_set.tsv`: add test_boolean_column column with
  manually-randomized choices.

- Add metadata.test_boolean_column to `input_file.ndjson`. Copied over
  from `small_metadata_set.tsv` using
  https://github.com/pflanze/ndjson-updater/.

- Add new column to test results; sorting changed because it is
  currently dependent on the hash of the object contents.
