[ws-proxy] Get supervisor image from pod annotation instead from ws-proxy config

[corneliusludmann]

Description

This PR removes the ws-proxy config value that specifies the supervisor image. Instead of using this config value, the supervisor image from the ImageSpec annotation is used. This …

1. allows deploying new supervisor images without the need to change the ws-proxy config + pod restart, and
2. supports that workspaces use different supervisor images.

Fixes #6512

How to test

• Make sure the unit tests pass
• Start a workspace, make sure there is no such error in the ws-proxy logs like no workspace information available - cannot resolve supervisor route
