Find an alternative to `nodegit` about coco HOT 2 CLOSED

This relates to #1, where the createCommit method would be replaced with something much simpler;

import simpleGit, { SimpleGit } from 'simple-git';

export async function createCommit(
  commitMsg: string,
  repoPath: string
): Promise<string | null> {
  const git: SimpleGit = simpleGit(repoPath);

  await git.add('.');
  await git.commit(commitMsg);

  return await git.revparse(['HEAD']);
}

The general adoption, along with the fact we don't need to support "in-browser" functionality is pushing me towards using simple-git.

Funny thing, the original prototype of coco was used simple-git however I replaced it with nodegit when adopting LangChain 🤦‍♂️ ... live and learn!
