Fresh lit+ts project does not build full dist

[Zoramite]

Describe the bug

When trying to use the boiler plate lit project the production build does not correctly export the files for serving.

After visiting in the browser I get a 404 error: Cannot GET /. I think that this is because there is not index.html generated in the dist? The dist only has two files: vite-project.js vite.svg.

Reproduction

https://stackblitz.com/edit/vitejs-vite-dkycbq?file=index.html

Steps to reproduce

npm create vite@latest
# Choose lit + typescript options
cd vite-project
npm install
npm run build
npx vite preview

Duplicate of #7009

It's because lit and lit-ts are library target configs instead of app target configs like others (react / vue). I've no idea why lit's templates are set to lib 🤔. It seems to be library target from the very beginning. 830f3d3
So no preview mode for lib mode.

But should we change lit & lit-ts to app target(seems like a breaking change) or document it in the CLI? For example Lit(library)

I was recently confused by this, strong vote to fix!

resolved in #12459. create-vite will create Lit applications as of @4.3.0
