Explore prompting to enable Cloud Changes on web

Verification

1. Ensure that you have a clean setup. We only show this for a new user who has never used insiders.vscode.dev before.
2. Open a GitHub URL such as https://insiders.vscode.dev/github/microsoft/vscode
3. Edit any file in the repo.
4. An overlay widget, such as the one shown below, should appear in the top right-hand corner of the editor when you have paused typing. The overlay widget should call out that you can access your changes across devices using Cloud Changes

Please verify that this dialog only appears once during your first session and that it does not interrupt your typing.

Should there be a picture of an overlay widget in the above comment? I think the comment mentions it but I can't see one.

Also, I tried this just now in an incognito window (after logging into github) and I didn't see an overlay widget? I had to use a non-msft repo because I can't authenticate the msft org from incognito.

@bhavyaus is there an experimental setting that folks need to set to see the overlay widget still?

I also can't seem to get this dialog to open up. I tried enabling workbench.welcome.experimental.dialog, but that didn't seem to make a difference.
