tcsh/Starship: Faulty alias 'precmd' removed

I'm trying to use zoxide with tcsh and Starship, but after installation and trying `z` for the first time I get this:

```
> z
__zoxide_args: Undefined variable
Faulty alias 'precmd' removed.
```

* zoxide: 0.9.8
* tcsh: 6.20.00 (Astron)
* Starship: 1.23.0
