### Summary

I would like to use ansible.builtin.get_url to download a file and check it against a SHA3 512 checksum. It appears that [hashlib](https://docs.python.org/3/library/hashlib.html) supports SHA3 and even uses it by default as of Python 3.9.

### Issue Type

Bug Report

### Component Name

get_url

### Ansible Version

```console
2.15.0
```

### Additional Information

<!--- Paste example playbooks or commands between quotes below -->
```yaml (paste below)
- name: Retrieve the file
  ansible.builtin.get_url:
    url: "https://example.com/file"
    checksum: "sha3_512:{{ file_checksum }}"
    dest: "file"
  vars:
    file_checksum: '{{ lookup("file", "file.sha3_512").split()[0] }}'
```
