remove bevy_log as a dev-dependency from bevy_asset (#18619)

# Objective

- the bevy workspace fails to publish
```
   Packaging bevy_asset v0.16.0-dev (/home/runner/work/bevy-releasability/bevy-releasability/crates/bevy_asset)
    Updating crates.io index
    Updating `kellnr` index
error: failed to prepare local package for uploading

Caused by:
  no matching package named `bevy_log` found
  location searched: `kellnr` index
  required by package `bevy_asset v0.16.0-dev (/home/runner/work/bevy-releasability/bevy-releasability/crates/bevy_asset)`
```

## Solution

- Remove bevy_log dev-dependency from bevy_asset
- Not sure of why this is a problem, but the dev-dependency is not
really needed so... 🤷
