chore: prepare tracing-subscriber 0.3.18 release (tokio-rs#2789)

# 0.3.18 (November 13, 2023)

This release of `tracing-subscriber` adds support for the [`NO_COLOR`] environment
variable (an informal standard to disable emitting ANSI color escape codes) in
`fmt::Layer`, reintroduces support for the [`chrono`] crate, and increases the
minimum supported Rust version (MSRV) to Rust 1.63.0.

It also introduces several minor API improvements.

### Added

- **chrono**: Add [`chrono`] implementations of `FormatTime` ([tokio-rs#2690])
- **subscriber**: Add support for the [`NO_COLOR`] environment variable in
`fmt::Layer` ([tokio-rs#2647])
- **fmt**: make `format::Writer::new()` public ([tokio-rs#2680])
- **filter**: Implement `layer::Filter` for `Option<Filter>` ([tokio-rs#2407])

### Changed

- **log**: bump version of `tracing-log` to 0.2 ([tokio-rs#2772])
- Increased minimum supported Rust version (MSRV) to 1.63.0+.
