fix(amazonq): Warn user Developer Profile not selected (aws#7160)

## Problem:

If a user has not selected Q Developer Profile after signing in, their
features will not work.

Some existing users, before the introduction of Q Developer Profiles,
who were already signed in had their features stop working because they
didn't select a profile.

## Solution:

On startup if we detect the user did not select a profile, then send a
warning message that their features will not work until they select one.
The message will have a button to allow them to select a profile through
quickpick, or entirly ignore the message and not show it again.
