Add config option to delete container volumes for failed runners

[joestump]

Feature Description

It took me entirely too long to figure out that failed Gitea runners leave behind orphaned volumes. What I can't seem to figure out is how to get Gitea/Act to nuke these things (or harvest them periodically?). Since the containers are removed, the volumes are orphaned and immune to pruning in Docker.

It looks like Act should be deleting these? https://github.com/nektos/act/blob/master/pkg/runner/run_context.go#L353-L354

But it's not clear if Gitea has a way to enable that functionality for failed jobs.

I think this belongs to act_runner repository: https://gitea.com/gitea/act_runner

@TheFox0x7 thank you for pointing me in the right direction. Looks like someone else reported this a couple months back. Closing this out – anyone else who sees this thread should hop on over to https://gitea.com/gitea/act_runner/issues/659
