core: prepare to release v0.1.30 (#2339)

# 0.1.30 (October 6, 2022)

This release of `tracing-core` adds a new `on_register_dispatch` method
to the `Subscriber` trait to allow the `Subscriber` to perform
initialization after being registered as a `Dispatch`, and a
`WeakDispatch` type to allow a `Subscriber` to store its own `Dispatch`
without creating reference count cycles.

### Added

- `Subscriber::on_register_dispatch` method ([#2269])
- `WeakDispatch` type and `Dispatch::downgrade()` function ([#2293])

Thanks to @jswrenn for contributing to this release!
