General setting for manual approval before commits

### Feature summary

The GitHub Copilot App automatically commits. I would like to have a feature setting to turn that off

### What problem are you trying to solve?

**Context:** I'm used to do commits manually in Git. While testing out the GitHub Copilot app, I noticed that the default behaviour seems to be that after "I am finished" is detected, the changes are commited. Unfortunately, I did not get a chance to review the changes.

In my case, I had it scan my customer facing documentation to search for gaps between the documentation and my memory bank. The update worked well, but I still wanted to iron out some changes. After writing "Please change sentence A to sentence B", I noticed another commit.

After writing "Don't do Git commits yourself. I need to manually say okay before you make a commit" the behaviour was as I wanted it. Then, I manually gave my go ahead.

---
Would it be possible to have either
- a general setting regarding commits
- a toggle somewhere in the prompt area like "allow auto-commits" that I can turn on/off in the session?
