attributes: prepare to release v0.1.21 (#2097)

# 0.1.21 (April 26, 2022)

This release adds support for setting explicit parent and follows-from
spans in the `#[instrument]` attribute.

### Added

- `#[instrument(follows_from = ...)]` argument for setting one or more
  follows-from span ([#2093])
- `#[instrument(parent = ...)]` argument for overriding the generated
  span's parent ([#2091])

### Fixed

- Extra braces around `async` blocks in expanded code (causes a Clippy
  warning) ([#2090])
- Broken documentation links ([#2068], [#2077])

Thanks to @jarrodldavis, @ben0x539, and new contributor @jswrenn for
contributing to this release!
