Do not report error on capturing clipboard, simply open quick open without clipboard contents

Testing #11645

In Safari, vscode.dev has a hard time capturing the clipboard for quick input, so the user gets this weird flow.

Instead of this, I argue it's best to simply avoid the error notification and open quick open without the clipboard contents. VS Code is getting out of its way to do something nice for the user, it should degrade gracefully and silently if unable to, instead of nagging the user.

Please forward this to core, if it's a bug in that domain.
