fix(amazonq): upgrade mynah to 4.23.1 (#6726)

## Problem
Previous mynah-ui upgrade included a regression which removed the `@`
from the context command name.

## Solution
Fix `@worskspace` regex now that @ is no longer removed. Upgrade mynah
to 4.23.1 https://github.com/aws/mynah-ui/releases/tag/v4.23.1
