Update README.md to make local installation more clear

AI Description

This pull request introduces changes to the README.md file, providing updated instructions for running the Toolkit application locally and in the cloud. The changes aim to enhance clarity and streamline the setup process for developers.

Changes:

• Local Setup: The section now includes a new subsection titled "Using make", which offers an alternative method for running the application locally using a Makefile. It provides a code snippet with commands to clone the repository, navigate to the project directory, and execute the make first-run command.
• Docker Compose: The previous "Docker Compose setup" section has been replaced with a new subsection titled "Docker Compose only". This section provides instructions for running Docker Compose directly without the Makefile, using the docker compose up command.
• Cloud Setup: A new section titled "Cloud" has been added, offering guidance for running the project in the cloud using GitHub Codespaces. It includes a link to the "Codespaces Setup Guide" for further reference.
