Add `prf:numref`

### Context

# Context

I see cross-reference with text in sphinx-proof with

```
:prf:ref:`text <proof-label>`
```

which only replaces the `proof-label` by `text`. Is there any way to use, for example

```
:prf:numref:`theorem %s <proof-label>`
```

as figure and table of sphinx?
