spring-roo 1.3.0

Closes #34382.

The .jar elements in bin seem to be mandatory now, roo errors out and refuses to load without them:

```
Error: Could not find or load main class
org.springframework.roo.bootstrap.Main
```

To deal with this I’ve sandboxed the directory and scripted them into the bin.
If you're feeling lovely: any chance of a wee test?
