Git branch name in the status bar

[stefano-cherchi]

Is your feature request related to a problem? Please describe.

While you're working on the notebook you can't see which branch you're working on, unless you select the Git extension tab. I noticed that this can be confusing and lead to errors especially for developers with limited experience on git.

Describe the solution you'd like

It would be nice to have the name of the current branch in the bottom status bar, next to the git status icon, like in VSCode or other IDEs.

Thanks for the suggestion. I can provide some pointers to implement this. I would only suggest to make it configurable as some users like not too crowded status bar.
