Dice Metric args are unclear

[sh3rlock14]

Hi there!
I was implementing a 3D volume segmentation model and hence I wanted to use torchmetrics Dice Score...
Alas, when I tried to use Dice I discovered that by setting some args, such as average = None, even if the docs let intend that is allowed, it is not!
Indeed: at row 140 there's:
average: Optional[Literal["micro", "macro", "weighted", "none"]] = "micro",,

but at row 166 we have:

if average not in ["micro", "macro", "samples"]:
    raise ValueError(f"The `reduce` {average} is not valid.")

I was also wondering if your Dice support the preds and the g_truth to be in "one hot format" (not one hot encoding: I am in a multi-class, multi-label scenario, so I can have more than one "1" along C dim).

Thanks in advance for your help 🙏🏻 !

I also stumbled upon the same issue, I think this is a bug in the library, see my comment: #1425 (comment)
