config(amazonq): increase supplementalContext timeout #5967

## Problem
based on data, we found out that 50ms cap is not sufficient for larger
repo and it tends to return empty supplementalContext due to timeout.

## Solution
Increase to 100ms for now and there will be action items for Q team to
collect p50, p75, p90 latency according to different repo size to
conduct a detailed investigation.
