subscriber: prepare to release v0.3.12 (tokio-rs#2187)

# 0.3.12 (Jun 29, 2022)

This release of `tracing-subscriber` adds a new `Layer::event_enabled`
method, which allows `Layer`s to filter events *after* their field
values are recorded; a `Filter` implementation for `reload::Layer`, to
make using `reload` with per-layer filtering more ergonomic, and
additional inherent method downcasting APIs for the `Layered` type. In
addition, it includes dependency updates, and minor fixes for
documentation and feature flagging.

### Added

- **layer**: `Layer::event_enabled` method, which can be implemented to
  filter events based on their field values (tokio-rs#2008)
- **reload**: `Filter` implementation for `reload::Layer` (tokio-rs#2159)
- **layer**: `Layered::downcast_ref` and `Layered::is` inherent methods
  (tokio-rs#2160)

### Changed

- **parking_lot**: Updated dependency on `parking_lot` to 0.13.0
  (tokio-rs#2143)
- Replaced `lazy_static` dependency with `once_cell` (tokio-rs#2147)

### Fixed

- Don't enable `tracing-core` features by default (tokio-rs#2107)
- Several documentation link and typo fixes (tokio-rs#2064, tokio-rs#2068, tokio-rs#2077,
  tokio-rs#2161, tokio-rs#1088)
