Improve Form Validation errors

At the moment, AMA prints something like:

```
❌ [ AMA ]: NO_UNDEFINED - The form validation has failed, but no component with an error was found
❌ [ AMA ]: NO_UNDEFINED - No next field found. Make sure you wrap your form inside the component
```

- [ ] Fix typos
- [ ] Replace NO_UNDEFINED with a Form related error code
- [ ] Add a link to the documentation
- [ ] Suggest usage of wrapping error message with ``
- [ ] Add an example for the point above in the documentation
