fixing the warning message

[tnylea]

When running npm run build or npm run dev, we are getting this warning:

npm run build                                                                                   ✔  01:04:13 PM 

vite v6.1.1 building for production...
transforming (1460) node_modules/lucide-vue-next/dist/esm/icons/sunset.js[@vue/compiler-sfc] withDefaults() is unnecessary when using destructure with defineProps().
Reactive destructure will be disabled when using withDefaults().
Prefer using destructure default values, e.g. const { foo = 1 } = defineProps(...).

This PR will fix that warning by removing the unnecessary withDefaults().
