feat(create-vite): align template styles with docs

[patak-cat]

Description

Fix #8385

Hopefully, this will help to make it more clear to users that these templates are a way to try out Vite with their favorite framework, but these aren't production-grade scaffolding tools that include the recommended setup for testing, linting, etc from each framework. Like Vue has done with create-vue, we should push other frameworks to off a similar tool (most of them are already working in complete frameworks like SvelteKit, maybe a create-svelte isn't a bad idea for example if it doesn't exist already).

The new docs-aligned theme should also make the experience better when reading the docs and jumping to the online StackBlitz playgrounds.

Changes include:

• All templates have a light/dark theme aligned with the new docs (except for the font, as I think we should include Inter in each of them. I still add it to the font family list in case it is installed locally)
• All are using the vite logo from the public dir. I think it is good for users to see this feature right away. Vite is also the favicon for every template, again to show that these are Vite first starters.
• All have two logos (vite + framework) that you can click to get to the docs
• All have a counter (added one for Preact and Vanilla templates)
• Removes recommendation for VS Code in Vue templates, Volar now works in several IDEs
• Adds recommendation to check out create-vue

Just to share, we have a create-svelte which allows you to run npm init svelte in order to create a new SvelteKit project

@benmccann nice! Looks like it creates a SvelteKit app, we already have a link to the SvelteKit docs in the templates with a call to action to check them out. I think that is good for Svelte here then.

Updated the brand colors, and styles of links and buttons

One suggestion but apart from that it LGTM 🚀
