fix(cli): use create-nitro-app instead of create-nitro for vp create nitro (#898)

This change explicitly maps `vp create nitro` to the maintained
`create-nitro-app` package, fixing the issue where users got an
unexpected Express template prompt instead of Nitro.

Note: This differs from pnpm's behavior where `npm create nitro` still
resolves to the `create-nitro`

close #888
