Describe the bug
When constructing a class that has a deprecated argument and both the new and deprecated argument are passed the construction fails. This may happen, for example, when using other libraries that automatically construct the classes from a yaml file.

To Reproduce

from monai.networks.nets import UNet
unet = UNet(spatial_dims=2, in_channels=1, out_channels=1, channels=(16, 32, 64), strides=(2, 2, 2), dimensions=None)

Expected behavior
The instance of UNet should be created.

Screenshots
The error happens on line 190 of monai/utils/deprecated.py:

if new_name is not None and name in kwargs:
    # replace the deprecated arg "name" with "new_name"
    kwargs[new_name] = kwargs[name]
