Consolidate create-vite templates

[patak-dev]

Clear and concise description of the problem

I think it would be good for users trying Vite through the starters to get a uniform experience when switching frameworks, making the templates more about "trying Vite" than the best starting point for each framework. All of them are now working on their own starters/frameworks, as these are best maintained out of the Vite monorepo. See for example https://github.com/vuejs/create-vue

Suggested solution

We can use a simplified version of the docs new theme (only the basic branding colors). If we want to keep it simple, we could only provide the dark mode version. And in each template we can have a big centered logo and something like "Vite + {Framework}", a link to Vite docs, and the framework docs. A counter, and a paragraph with useful information (since several templates already do that)
