Allow Continue On cloning from codespace to local on desktop VS Code

[joyceerhl]

In virtual workspaces, the file dialog has a Show Local button. There's no such dialog in remote windows--the file dialog always shows the remote filesystem. This is an issue for continuing from a GitHub codespace to a local desktop clone when the user is in VS Code desktop.

Suggestion: when in a virtual or remote window on desktop, always have the 'Show Local' option in the file dialog.

Oh interesting--there is a Show Local in the Open Folder flow, but not when the git extension invokes the file dialog:

I see this was an intentional decision for extension access to the simple file dialog in a remote window in addaad3 for #110264

However that makes it hard to go from a remote window to a local one from extension land. Is this something that we can expose to extensions via a new proposed api option for the file dialog?

Duplicate of #131138, which is an API request to expose "show local".

Reopening this to track adoption of #131138 in the Continue On flow.

Steps:

Open a codespace in VS Code desktop
From the remote indicator, choose Continue in Local Clone
Ensure that the repo gets cloned successfully to your local machine
