Generate GPG signature for commit when edit a file in web editor

Description

Generate GPG signature for commit when edit a file in web editor.

Overview

When I edit a file in web editor and make a commit or accept a merge request, this commit isn't signed. Maybe add an option for new GPG key generation for the user. After it, these commits are signed with the GitLab generated key.

Use cases

• Edit file in web editor
• Accept merge request
