Handle ``dbhtml`` elements

### 📝 Description of the feature

``dbhtml`` elements need to be handled properly.

``TRLCY`` original documentation:
```

```

Renders as follows in ``trlcy`` pydocstring:
```py
filename="Hlp_G_BAS11_3.html"?
```

Whereas it should point to the proper file with the link mentioned in the ``ans_bas.db`` file.

### 🔗 Useful links and references

_No response_

Read the TRLCY reference and compare the original dbhtml example with its current rendering in trlcy pydocstring. Trace how the ans_bas.db link is resolved, then verify that the example points to the proper file rather than emitting the filename text.
