Add support for tailwind.prefix config

[obedm503]

shadcn/ui supports setting a prefix in the config. This is especially useful when integrating tailwind in legacy projects.

This is what it looks like in the components.json:

{
  "tailwind": {
    "prefix": "tw-"
  }
}

My current workaround is to add the prefix to every component manually. Please add support for the tailwind prefix.

Thanks for the suggestion :)
I'm currently in the process of rebuilding the cli so this is the perfect spot for this kind of issue/wish.

At first I wanted to skip the prefix option but it looks like there is indeed some need.
Can you explain what the actual benefits are or how it's important for legacy projects?
