[`doc_markdown`] Recognize words followed by empty parentheses `()` for quoting

*Please write a short comment explaining your change (or "none" for internal only changes)*

changelog: [`doc_markdown`] Recognize words followed by empty parentheses for quoting, e.g. `func()`.

---

Developers often write function/method names with trailing `()`, but `doc_markdown` lint did not consider that.

Old clippy suggestion was not very good:

```patch
-/// There is no try (do() or do_not()).
+/// There is no try (do() or `do_not`()).
```

New behavior recognizes function names such as `do()` even they contain no `_`/`::`; and backticks are suggested outside of the `()`:

```patch
-/// There is no try (do() or do_not()).
+/// There is no try (`do()` or `do_not()`).
```
