add type for djangoVitePlugin "list mode"

[scratchmex]

fixes

Argument of type 'string[]' is not assignable to parameter of type 'PluginConfig'.

when doing

import { defineConfig } from 'vite'
import djangoVite from 'django-vite-plugin'

export default defineConfig({
    plugins: [
        djangoVite([
            'app/tailwind.css',
        ])
    ],
})
