[feat req] Git-generated artifact name

[ModischFabrications]

What would you like to be added?

I would like an option to generate unique names based on the git state instead of the generic name "artifact".

This is my current workaround (output define, extra step, variable expansion later): https://github.com/ModischFabrications/turn_indicator_pcb/actions/runs/6606497177/workflow#L28

which results in a string like "turn_indicator_pcb_master_6606497177_2023-10-23"

Why is this needed?

I want to archive the resulting artifacts, but the default implementation doesn't offer a simple way to give unique names.

This could be easily solved with #349:
You generate the name with git and just upload the artifact as-is.
