Feature(Nuxt): Integerate nuxt/tailwindcss (and UnoCSS?) module

[MuhammadM1998]

Describe the feature

When using shadcn-nuxt, the user needs to add nuxt/tailwindcss module and run the cli to add the tailwind.config and tailwind.css files. This can be handled automatically by nuxt module which gives the following benefits

• More streamlined process: Most if not all Nuxt modules attempts to provide an out-of-the-box without any extra setup. This will help achieve this
• We have total control: This means we can not just add an integeration for tailwind, but also for UnoCSS (I know it's crazy, maybe UnoCSS support?  #34) out of the box too! We just need to know the correct configuration and implement it in a template then run the corresponding template based on user options.

I can take a stab at this if it seems good to you (Just the tailwind integration for now)!
