fix(amazonq): enable local workspace server through flare (#7089)

## Problem
local workspace context has been added to flare and its needed for
falcon changes

## Solution
we don't have `aws.q` settings in vscode so we have to use the language
server middleware to send back the settings

Once local workspace context is fully working and in the manifest I'll
uncomment
