Workflow tutorial

[dario-coscia]

Describe the bug The workflow to export tutorial contains workflow_dispatch which is not supported by the action jitterbit/get-changed-files@v1. This action is needed to see the changes done by the tutorials, see https://github.com/jitterbit/get-changed-files/issues/38

Additional context I suggest modifying the workflow to work as follow:

• On workflow_dispatch: Export all tutorial files.
• On push to master or dev: Export only changed tutorial files
