feat: Introduce duplicated_error option

[ovr]

Hello!

Thanks

Shouldn't we perhaps always throw an error in case an artifact with the same name already exists? What do you think?

GitHub doesn't give an ability to restart specific jobs in a workflow, it's why the whole workflow with all jobs can be restarted. In this case, I am getting a problem with this error, because I have jobs that depend on the job that failed.

Let's imagine

Jobs (step1) -> Job2.1 (step2) -> Job (step3)
                      -> Job2.2 (step2)

For example Job 2.1 success (uploaded artifact), but Job 2.1 failed
I will try to restart the whole workflow and job 2.1 will be failed because it already uploads an artifact
