Throws an Error when used without Git

**Describe the bug**
When using a VCS like JJ, the extension crashes with "Unable to Connect to the GitHub API, please check your internet connection."

**To Reproduce**
Steps to reproduce the behavior:
1. Put `git.disabled` in your .vscode/settings.json
2. Open actions pane

**Expected behavior**
It shouldn't require the Git extension, only provide optional features (like current branch).

**Extension Version**
`v0.27.1`

**Additional context**
Feel free to close as wontfix, I know this isn't exactly the recommended workflow :)
As I think about it, can you even figure out the connected repo without Git? IDK.

Reproduce el fallo estableciendo git.disabled en .vscode/settings.json y abriendo el panel de acciones. Traza la ruta de inicio de la extensión que crea el proveedor dependiente de Git y, a continuación, verifica que el panel de acciones se abra sin la extensión de Git, aunque las funciones opcionales, como la rama actual, pueden no estar disponibles.
