docs: update to database_prefix and 2.x version (#142)

- Front page: Update to indicate 2.0-2.1 pre-release coverage
- Rename database.schema_prefix to database.database_prefix
- Rename DJ_SCHEMA_PREFIX to DJ_DATABASE_PREFIX

This aligns with datajoint-python PR #1351 which renames the setting
to avoid confusion with store's schema_prefix (schema-addressed storage).
