fix(core): remove CRA migration logic from nx init

## Current Behavior
`nx init` has a special code path for Create React App (CRA) projects
that installs Vite-related dependencies incompatible with `@nx/vite`
when Vite 8 is resolved, causing failures for npm workspaces.

## Expected Behavior
CRA projects are no longer special-cased in `nx init`. They flow
through the normal npm repo path, which detects plugins like `@nx/vite`
via the standard `detectPlugins()` mechanism.

## Related Issue(s)
Fixes NXC-4107
