feat: add --manual-commit flag

WIP

Great future! Will multi-gitter still open the PR/MR as long as the script does the commits? That is not really clear from the docstring for me.

Will multi-gitter still open the PR/MR as long as the script does the commits? That is not really clear from the docstring for me.

This is indeed how it works. Do you have a suggestion to make it clearer while not being too long?

Suggested change

	cmd.Flags().BoolP("manual-commit", "", false, "Don't automatically commit changes. The script must commit the changes itself. Multiple commits are allowed.")
	cmd.Flags().BoolP("manual-commit", "", false, "Let the script commit the changes, multiple commits are allowed, Multi-gitter will still open a pull request when changes are detected.")

@tomasvanrijsse Please test this branch and verify if it's working as you would expect.

I used this branch with the --manual-commit flag to add multiple commits with the script while multi-gitter handled the branch/merge request creation with GitLab. It seems to work well. I would love to incorporate this in my workflow.

What would this PR need before it could be merged?
