chore: add NPM token config without corrupting .npmrc

OK, this was pretty funny in the end. The base `.npmrc` didn't have a trailing line break, so this command:

```
echo '//registry.npmjs.org/:_authToken=${NPM_TOKEN}' >> .npmrc
```

Turned the file into this:

```
auto-install-peers=true
workspaces-update=false//registry.npmjs.org/:_authToken=${NPM_TOKEN}
```

That explains both why:

1. The auth didn't work.
2. The workspace refs stopped updating.

The solution herein is to add a preceding line break, unconditionally.
