fix: installation error when installing amazon q in remote AND you have the extension locally (#4889)

## Problem
- due to a bug in https://github.com/microsoft/vscode/pull/206381/files#diff-efa08c29460835c0ffa740d751c34078033fd6cb6c7b031500fb31f524655de2R360 installExtension will fail on remote environments when the amazon q extension is already installed locally

## Solution
- install the amazon q extension using the vscode cli

## Alternatives considered
- Installing directly from github releases if they're on a remote environment. Its unclear though if the user will always be able to reach github (vs marketplace which is required to install extensions anyways)

## Drawbacks
- If the user doesn't have the vscode cli (though I think it autoinstalls in remotes?) then this won't work
