core: prepare to release v0.1.27 (tokio-rs#2155)

# 0.1.27 (June 7, 2022)

This release of `tracing-core` introduces a new `DefaultCallsite` type,
which can be used by instrumentation crates rather than implementing
their own callsite types. Using `DefaultCallsite` may offer reduced
overhead from callsite registration.

### Added

- `DefaultCallsite`, a pre-written `Callsite` implementation for use in
  instrumentation crates ([tokio-rs#2083])
- `ValueSet::len` and `Record::len` methods returning the number of
  fields in a `ValueSet` or `Record` ([tokio-rs#2152])

### Changed

- Replaced `lazy_static` dependency with `once_cell` ([tokio-rs#2147])

### Documented

- Added documentation to the `callsite` module ([tokio-rs#2088], [tokio-rs#2149])

Thanks to new contributors @jamesmunns and @james7132 for contributing
to this release!

 # 0.1.26 (April 14, 2022)
 
 This release adds a `Value` implementation for `Box<T: Value>` to allow
 recording boxed values more conveniently. In particular, this should improve
 the ergonomics of the implementations for `dyn std::error::Error` trait objects,
-including those added in [v0.1.25].
