`fs.rm` behavior is different from Node.js

Version: Deno 2.6.4 Node 25.3.0
OS: Linux

Reproduce:

```js
// main.js
import fs from 'node:fs/promises';

await fs.rm('bar');
```

- `mkdir foo`
- `ln -s foo bar`
- `node main.js` -> No errors
- `ln -s foo bar`
- `deno --allow-all main.js` -> Uncaught (in promise) SystemError: Path is a directory: rm returned EISDIR (is a directory) bar
