### Describe the issue

Attempting to use the orient_normals_consistent_tangent_plane method in Open3D, the function does not recognize lambda as a valid argument name.

### Steps to reproduce the bug

```python
import numpy as np
import open3d as o3d
points = np.random.random((100,3))
pcd = o3d.geometry.PointCloud(o3d.utility.Vector3dVector(points))
pcd.estimate_normals()
pcd.orient_normals_consistent_tangent_plane(k=5, lambda=0.1)
```

### Error message

SyntaxError: invalid syntax

### Expected behavior

Just an other name for the argument lambda for example lambda_
