feat(nuxt-module): auto inject lib/utils & refresh the playground

[MuhammadM1998]

This PR is an initial step to improve the nuxt module for shadcn-vue. Huge thanks to https://github.com/ineshbose for helping me out!

Module Changes

• Injected lib/utils by the module into buildDir. Now the CLI don't need to inject this file in Nuxt projects, making the file tree more cleaner. An alias for @/lib/utils is created to point the injected file for backward compatibility. Also a soft warning is displayed if a lib/utils file is found in the root and recommends to remove it as it's redundant.
• Bumped deps (Notably @nuxt/module-builder which resolves an harmless but annoying warning)

Playground Changes

• Fixed the issue of tailwindcss classes not applied because nuxtjs/tailwindcss was installed but not added to playground's modules
• Generated missing tailwind.css by the CLI
• Bumped Button component by the CLI
• Refreshed the playground style as it was really dull to me and added a dark mode switch (with tailwindcss and radix-vue/icons which are already dependencies)

Before	After

Next Steps

I'll create an issue for those to discuss them first

• Resolve this Feature(Nuxt): Pass components.json options to the module #271 by passing the components.json options to the module then reading them from the CLI when in a Nuxt project
• Auto install & configure nuxtjs/tailwindcss module
• Auto install & configure nuxtjs/color-mode module
