fix(amazonq): security: disable auto linkify of text links in chat aws#6449

## Problem
- Links incoming from Q responses can redirect to a vulnerable site
depending on the used context from the files.

## Solution
- Linkify strategy is updated to only accept links with `[TEXT](URL)`
format. (through MynahUI version
[4.21.6](https://github.com/aws/mynah-ui/releases/tag/v4.21.6))
