Is there an existing feature request for this?

• [X] I have searched the existing issues.

Command

No response

Description

Add sign-off and GPG sign for commits.

Reasoning

Signing a commit in git is a necessary thing to ensure that the commit was initiated by a validator.

Additional context and comments

In commits, the command I often use is git commit --signoff -S I wish there was an option added to melos version
