What would you like to be added?

It would be nice to have a option to allow overwrite existing artifacts like it was possible in v3.

Why is this needed?

I have an optional workflow step to sign artifacts, it downloads an artifact, signs it and uploads it with the same name again. Worked perfectly fine with actions/upload-artifact@v3.
I tried to use geekyeggo/delete-artifact@v2 but even that doesn't work.
Since this step is not applicable for pull requests, it would make things quite complicated to continue with separate artifact names.
