[BUG] Getting Started references old Wrangler, doesn't work as expected

### What version of `workers-rs` are you using?

Newest

### What version of `wrangler` are you using?

3.5.1

### Describe the bug

Our "Getting Started" Information references an old version of Wrangler, and doesn't appear to work with either 2.x or the latest version. When I follow the steps in our guide, I end up with a default Javascript project being created. I don't get the expected src/lib.rs starting point.

### Steps To Reproduce

1. Run steps from Getting Started guide:
```
npm init cloudflare project_name worker-rust
cd project_name
```
2. Follow prompt from wrangler / create-cloudflare
3. Look inside the src/ folder that is created'
4. Observe that you see `worker.js` and no rust-specific template
