attributes: prepare to release v0.1.24 (#2574)

# 0.1.24 (April 24th, 2023)

This release of `tracing-attributes` adds support for passing an
optional `level` to the `err` and `ret` arguments to `#[instrument]`,
allowing the level of the generated return-value event to be overridden.
For example,

```rust
#[instrument(err(level = "info"))]
fn my_great_function() -> Result<(), &'static str> {
    // ...
}
```

will emit an `INFO`-level event if the function returns an `Err`.

In addition, this release updates the [`syn`] dependency to v2.x.x.

### Added

- `level` argument to `err` and `ret` to override the level of the
  generated return value event (#2335)
- Improved compiler error message when `#[instrument]` is added to a
  `const fn` (#2418)

### Changed

- Updated `syn` dependency to 2.0 (#2516)

### Fixed

- Fix `clippy::unreachable` warnings in `#[instrument]`-generated code
  (#2356)
- Removed unused "visit" feature flag from `syn` dependency (#2530)

### Documented

- Documented default level for `err` (#2433)
- Improved documentation for levels in `#[instrument]` (#2350)

Thanks to @nitnelave, @jsgf, @Abhicodes-crypto, @LukeMathWalker,
@andrewpollack, @quad, @klensy, @davidpdrsn, and @dbidwell94 for
contributign to this release!

 # 0.1.23 (October 6, 2022)
 
 This release of `tracing-attributes` fixes a bug where compiler diagnostic spans
 for type errors in `#[instrument]`ed `async fn`s have the location of the
 `#[instrument]` attribute rather than the location of the actual error, and a
 bug where inner attributes in `#[instrument]`ed functions would cause a compiler
 error.
+
 ### Fixed
 
 - Fix incorrect handling of inner attributes in `#[instrument]`ed functions ([#2307])
