Add missing modelfetch package version to create-modelfetch CLI (#103)

## Summary
- Added the missing `modelfetch` package version to the
`packageVersions` object in the create-modelfetch CLI
- This ensures new projects scaffolded with create-modelfetch can
properly reference the main modelfetch package

## Test plan
- [ ] Run `pnpm exec nx run create-modelfetch:build` to verify the build
succeeds
- [ ] Test scaffolding a new project with the CLI to ensure the
modelfetch package version is correctly included
