Add Release Note (feature): The experimental git survey command (which was never upstreamed to the core Git project) was deprecated and [converted into a small shim on top of git repo structure](https://github.com/git-for-windows/git/pull/6268). In the future, git repo structure should be used instead, as the git survey command will be retired eventually.
