Switch away from workspace-defined dependencies (#614)

Both Dependabot and `cargo-edit`'s `cargo upgrade` don't seem
to handle dependencies being specified in the Cargo workspace
`Cargo.toml` and inherited by individual crates.

As such, this switches back to specifying those dependencies
explicitly in each crate. Dependabot always updates dependencies
across all crates, so they will still stay in sync.

Hopefully this change will fix:

```
updater | 2023/11/17 15:48:21 INFO <job_751330580> No update possible for libcnb 0.15.0
```

Seen in:
https://github.com/heroku/buildpacks-jvm/network/updates/751330580

I've left the local shared crate dependencies as workspace-defined,
since Dependabot or `cargo-edit` doesn't need to update those,
since they are path-only dependencies.

Lastly, the lists of dependencies have been sorted alphabetically.
