fix(amazonq): @workspace command shown in all tab types #6022

## Problem
The `@workspace` [context
command](https://github.com/aws/mynah-ui/blob/main/docs/DATAMODEL.md#contextcommands-default-)
is being shown in all tab types, even though it is only relevant to
Amazon Q chat ('cwc' tabType).

## Solution
Move the context command to the tab specific config file. This change
also allows other tab types to specify their own context commands if
applicable.
