npx vitepress init does not install the vitepress dependency in package.json

[glennsc]

Describe the bug

Running npx vitepress init and following the default prompts leaves you with a package.json with the vitepress scripts, but no dependency on vitepress itself, so the scripts don't run.

I looked through closed issues and don't see any indication this is by design.

Reproduction

mkdir vp1
cd vp1
npx vitepress init

Take defaults on every prompt. Result:

> vp1 npm run docs:dev

> docs:dev
> vitepress dev

sh: vitepress: command not found

Expected behavior

The vitepress dependency would have been installed.

Currently, this is by design. The docs state: "After installation, start the wizard by running: ...". We can do that probably though. I'll have to check why it was not added earlier 👀

This tripped me up too, as many other npx ... commands for creating projects do include the software used in the dependencies, normally you don't need to do npm add -D ... and npx ... init
