[Enhancement] Add document type for cv/resume

### Before submitting

- [x] I am using the latest version of Quarkdown.
- [x] I have checked the [wiki](https://quarkdown.com/wiki) to confirm this feature doesn't already exist.
- [x] I have searched existing [issues](https://github.com/iamgio/quarkdown/issues) for duplicates.

### Description

It isn't clear today how to create a CV or resume using quarkdown.

### Proposed syntax or behavior

```markdown

```

### Additional context

_No response_

No file, test, entry point, or proposed syntax is provided. Start by reviewing the linked wiki and existing Quarkdown document types, then define the CV/resume syntax and behavior. Done means the feature is usable for creating a CV or resume and its usage is documented.
