Vite ruby plugin causes server options to be ignored

[troubleshooting section]: https://vite-ruby.netlify.app/guide/troubleshooting.html

- [x] I have tried upgrading by running `bundle update vite_ruby`.
- [x] I have read the __[troubleshooting section]__ before opening an issue.

### Description 📖

`RubyPlugin` in vite config causes server options like `host` or `port` to be ignored.

### Reproduction 🐞

_Please provide a link to a repo that can reproduce the problem you ran into._

``` sh
rails new vite-rails-test
cd vite-rails-test
bundle add vite_rails
bundle install
bundle exec vite install
./node_modules/vite/bin/vite.js --host=0.0.0.0
```

Expected:

```
VITE v5.4.19 ready in 766 ms

➜ Local: http://localhost:5173/
➜ Network: http://192.168.1.171:5173/
➜ press h + enter to show help
```

Actual:

```
VITE v5.4.19 ready in 108 ms

➜ Local: http://localhost:3036/vite-dev/
➜ press h + enter to show help
```

The bug goes away if `RubyPlugin` is commented out in `vite.config.mts`
