🐛 Bug: package.json `""` author.name not changed by set Git user

### Bug Report Checklist

- [x] I have tried restarting my IDE and the issue persists.
- [x] I have pulled in the newest version of the project.
- [x] I have [searched for related issues](https://github.com/JoshuaKGoldberg/create-typescript-app/issues?q=is%3Aissue) and found none that matched my issue.

### Expected

I intentionally have my global gitconfig include the following:

```gitconfig
[user]
name =
email =
useConfigOnly = true
```

And I have an alias to easily set up a per-repository user configuration. It is part of my workflow where I use this to help separate my work repositories from my personal repositories.

The expected behaviour is that the command should create the repository successfully and pass the initial `pnpm lint --fix`

### Actual

When initializing a new repository with `create-typescript-app --preset everything`
```
● Tip: to run again with the same input values, use: npx create-typescript-app --description "grab bag of random projects" --email "[object Object]" --preset everything

■ The pnpm lint --fix script failed. You should re-run it and fix its complaints.

After which, I set up my user name with

```
# ~repos/disordered main
» git config-user -h
'config-user' is aliased to '!git config --local user.name "$1" && git config --local user.email "$2" && :'

# ~repos/disordered main
» git config-user 'Emily M Klassen' 'hello@forivall.com'
