Add vue version for vite and webpack

What does this merge request do and why?

Tracking them separately helps to create two usable but configurations between vite and webpack.

How to set up and validate locally

1. Ensure Vite is enabled by adding the below configuration in gdk.yml, and set the vue version to 3:

---
vite:
  enabled: true
  vue_version: 3

1. Check out to this merge request's branch.
2. Run gdk reconfigure to check if regenerating all configuration is successful.
3. Do the same, but for a webpack block instead
