Small documentation fix

It's nothing major, but it had me confused. In step 3 it's probably better to use the following code:

```
<%- paginate(posts) %>
```

(The <%- in EJS is not very well documented and it took me too long to figure that one out)

Find the documentation file referenced in the issue (likely a README or guide). Locate step 3 and replace the pagination code snippet with `<%- paginate(posts) %>`. Verify the change by checking the rendered output in a browser or preview tool to ensure the EJS tag works correctly.
