Cloning Flutter SDK via VS Code doesn't enable non-stable branch selection

[anderdobo]

When you clone the Flutter SDK with the flow provided in VS Code, you don't get the option to switch to channels other than stable.

Recommendation: Users who install the SDK through the flow offered in VS Code should have the ability to switch to all the available channels (currently master, main, beta and stable).

Oof, good catch. This is probably because of --single-branch here which I thought would improve performance (less data needs to be downloaded) and didn't consider this.
