feat(amazonq): Reduce @workspace indexing time by 50% (#5519)

## Problem

The indexing of @workspace feature is slow.

## Solution

By upgrading ONNX version from 1.18 to 1.19 in the 0.1.5 LSP, we
observed reduction in indexing time by about 50% when using CPU for
index. There is no improvement when using GPU or AMD CPU on Windows.
There is no customer facing change or customer experience change.
