Upgrade VitePress to use Vite v6

I recently upgraded my project to use Vite v6. However, I encountered type conflicts between VitePress and my project due to VitePress using Vite v5. The error message is as follows:

Additional context

The plugins causing this issue are vite-plugin-vue-devtools and vite-plugin-vuetify. These plugins are used in the Vite configuration within VitePress:

export default defineConfig({
    ...
    vite: {
        ...
        plugins: [
            vueDevTools(),
            vuetify({
                autoImport: true,
                styles: { configFile: "../../src/styles/settings.scss" }
            })
        ],
    ...
})

It is planned (#4467). Some features don't work properly, but you can force vite 6 using overrides (npm, pnpm). It should work fine if you're not using data and path loaders.
