I can't switch session from worktrees to local

### Short summary

I lost the option to switch from worktrees to local

### Affected version or release

1.1.9

### Installation context

_No response_

### What happened?

In latest Windows version 1.1.9, it removed the option for us to switch between local VS worktree. I want it back!
The worktree doesn't work for our projects as our repo has a lot of submodules. It's not convenient to checkcout a worktree. There's no way to build and test in a worktree. It's broken. Please bring the settings back.

### Steps to reproduce
**Before**:

**After**:

### Expected behavior
I can let Copilot just update my code in current branch, so I can build and test there.

### Additional context

_No response_

Reproduce el problema en Windows con la versión 1.1.9 y compara las capturas de pantalla Before y After. Rastrea la configuración que permite elegir entre worktrees y la rama local actual, y verifica después que la opción de cambio esté disponible y que Copilot pueda actualizar la rama actual para proyectos que usan submódulos.
