Fix formatting of lambda star arguments (#6257)

## Summary
Previously, the ruff formatter was removing the star argument of
`lambda` expressions when formatting.

Given the following code snippet
```python
lambda *a: ()
lambda **b: ()
```
it would be formatted to
```python
lambda: ()
lambda: ()
```

We fix this by checking for the presence of `args`, `vararg` or `kwarg`
in the `lambda` expression, before we were only checking for the
presence of `args`.

Fixes #5894

## Test Plan

Add new tests cases.
