Signed-off-by: Packit <hello@packit.dev> -- what is the purpose and meaning?
### What happened? What is the problem?

I see the commits in Fedora dist-git by packit have `Signed-off-by: Packit <hello@packit.dev>` in the commit messages.

 - This is not required in Fedora, EPEL, RHEL, CentOS Stream. There is nothing to sign off.
 - How can a robot/program legally sign anything off? What does this even mean?

### What did you expect to happen?

No `Signed-off-by: Packit <hello@packit.dev>`.

### Example URL(s)

_No response_

### Steps to reproduce

_No response_

### Workaround

- [ ] There is an existing workaround that can be used until this issue is fixed.

### Participation

- [ ] I am willing to submit a pull request for this issue. (Packit team is happy to help!)
