📚 Description

This pull request intends to do two things namely:

1. Refactor the Shadcn Vue CLI: Before this PR, the PROJECT_DEPENDENCIES object had two properties namely: base and nuxt but now it only has the base as its property. In the base array we have 5 dependencies that get installed when initializing the Shadcn Vue CLI as long as the framework selected is not Nuxt. In the nuxt array we only had the @nuxtjs/tailwindcss module which got installed if you selected nuxt as your preferred framework but this doesn't look right because we could install this alongside the shadcn-nuxt module allowing for separation of concerns. This PR intends to fix this issue by allowing the dependencies in the base array to be installed in all the frameworks including Nuxt because the issue raised here states that the shadcn-nuxt module doesn't install any dependencies. This PR intends to fix that.
2. Refactor the shadcn-nuxt module: This PR intends to refactor the shadcn-nuxt module by installing the required modules ( @nuxtjs/color-mode and @nuxtjs/tailwindcss ) and thus allows for the separation of concerns between the module and the CLI. In simple terms, the CLI handles general functionalities while the module ( shadcn-nuxt ) handles specific functionalities related to Nuxt.
