fix(amazonq): temporarily disable q developer profiles (#7118)

## Problem
q developer profiles are being fetched by VSCode + flare on the same
token causing requests to be throttled

## Solution
temporary disable profile fetching. The real solution will need to be
implemented in flare, which should disable profile fetching by default
for VSCode?
