The only reason we need the Extended Services in the Serverless Logic Web Tools is to use the CORS Proxy we have inside it to interact with OpenShift and Service Registries without being blocked by CORS policies.

After this PR , the CORS Proxy will be moved from the Extended Services to a new package, which will be deployed in favor of our current git-cors-proxy deployment.

The goal of this task is to remove the Extended Services from Serverless Logic Web Tools, which includes making changes in the code itself, quickstart guides, env vars, and GitHub workflows.

Since we have many references of the Extended Services in the docs, updating them is also part of this task.
