fix(dprint): Run rustfmt with nightly

We must do this if we want `dprint` to respect some of the unstable
options we have configured in our `rustfmt.toml`. This is what we get
if we run `cargo fmt` (as opposed to `cargo +nightly fmt`):

```
Warning: can't set `wrap_comments = true`, unstable features are only available in nightly channel.
Warning: can't set `comment_width = 100`, unstable features are only available in nightly channel.
Warning: can't set `imports_granularity = Item`, unstable features are only available in nightly channel.
Warning: can't set `group_imports = One`, unstable features are only available in nightly channel.
```

After running `dprint fmt` with the new configuration we can see that
the autoformatter consistently applies `group_imports = One` to our
codebase.
