Keep workspace:* protocol in react-on-rails-pro package.json (#2177)

## Summary
- Removes unnecessary manual conversion of `workspace:*` to explicit
version during release
- Restores `workspace:*` in `packages/react-on-rails-pro/package.json`

Fixes #2176

## Details

The release script (`rakelib/release.rake`) was manually converting
`workspace:*` to an explicit version in
`packages/react-on-rails-pro/package.json` during release. This is
**unnecessary** because pnpm automatically handles this conversion
during `pnpm publish`.

### How pnpm handles workspace:* 

When running `pnpm pack` or `pnpm publish`, pnpm dynamically replaces
`workspace:*` with the corresponding version. This is documented
behavior: https://pnpm.io/workspaces

### Verified locally

```bash
# 1. Set dependency to workspace:*
# 2. Run pnpm pack
# 3. Extract tarball's package.json
# Result: "react-on-rails": "16.2.0-beta.13" (exact version)
```

### Benefits

- **Cleaner development experience** - Developers see `workspace:*`
indicating a workspace dependency
- **No spurious git changes** - The dependency line won't change on
every release
- **pnpm best practice** - Let the tool handle what it's designed for
- **Simpler release script** - Less code to maintain

## Test plan
- [x] Verified `pnpm pack` converts `workspace:*` to exact version in
tarball
- [x] Confirmed published package.json in tarball has correct version
