subscriber: prepare to release v0.2.20

# 0.2.20 (August 17, 2021)
### Fixed

- **fmt**: Fixed `fmt` printing only the first `source` for errors with
  a chain of sources ([#1460])
- **fmt**: Fixed missing space between level and event in the `Pretty`
  formatter ([#1498])
- **json**: Fixed `Json` formatter not honoring `without_time` and
  `with_level` configurations ([#1463])

### Added

- **registry**: Improved panic message when cloning a span whose ID
  doesn't exist, to aid in debugging issues with multiple subscribers
  ([#1483])
