addapting pipeline to follow drone.yml config

This PR optimizes the GitHub Actions workflow for improved performance and readability. Key enhancements include:

Shallow Git Clone: We've updated the Git clone step to use a shallow clone with a depth of 1, reducing the amount of data fetched during the clone operation.

Dependency Caching: Caching of dependencies, such as Node.js modules, using GitHub Actions cache. This helps in reducing build times for subsequent runs
