serde: prepare to release 0.1.3 (tokio-rs#1904)

# 0.1.3 (February 4, 2022)

This release adds *experimental* support for recording structured field
values using the [`valuable`] crate. See [this blog post][post] for
details on `valuable`.

Note that `valuable` support currently requires `--cfg
tracing_unstable`. See the documentation for details.

### Added

- **valuable**: Experimental support for serializing user-defined types
  using [`valuable`] and [`valuable-serde`] ([tokio-rs#1862])
- Support for serializing `f64` values ([tokio-rs#1507])

### Fixed

- Fixed incorrect size hint in `SerializeFieldSet` ([tokio-rs#1333])
- A number of documentation fixes

Thanks to @akinnane and @maxburke for contributing to this release!

(I also noticed there was a missing changelog entry for v0.1.2, so I
fixed that while I was here)
