Red Knot shows types for literal expressions on hover

Minimal reproducible example ([playground](https://playknot.ruff.rs/ca9df1f1-6ebb-4063-a3d0-91b476f40efa)):

```python
print(
    0  # Hover: `Literal[0]`
)

def f():
    '''Lorem ipsum dolor sit amet.'''  # Hover: `Literal["Lorem ipsum dolor sit amet."]`
```

This information is, arguably, redundant and should not be emitted.
