`vp up` in monorepo changes vite dependency in package.json from catalog to exact version

[maxdzin]

Describe the bug

In just-created vp monorepo with pnpm, package.json has dev dependency "vite": "catalog:".

By launching vp up, dependencies are updated properly in pnpm-workspace.yaml and vite is set there as:

catalog:
  ...
  vite: npm:@voidzero-dev/vite-plus-core@0.2.7
  ...

but package.json vite dependency is changed from catalog: to npm:@voidzero-dev/vite-plus-core@0.2.7

What is expected:
After vp up package.json vite dependency should be preserved as "vite": "catalog:".

What happening actually:
After vp up package.json vite dependency is changed from "vite": "catalog:" to "vite": "npm:@voidzero-dev/vite-plus-core@0.2.7".

Reproduction

Steps to reproduce

1. vp create vite:monorepo - select pnpm as package manager and complete installing.
2. Check package.json: vite dependency is set as "vite": "catalog:" there.
3. Run vp up.
4. Check package.json: vite dependency is changed now to "vite": "npm:@voidzero-dev/vite-plus-core@0.2.7", but should be preserved as "vite": "catalog:".
