git: Add notification to git clone (#41712)

Adds a simple notification when cloning a repo using the integrated git
clone on Zed. Before this, the user had no feedback after starting the
cloning action.

Demo:

Not sure about that icon I'm using for the animation, but that can be
easily changed.

Release Notes:

- Added notification when cloning a repo from zed
