Update index.js, package_installer.bat, and CONTRIBUTE.md

This commit includes updates to the src/index.js, package_installer.bat, and CONTRIBUTE.md files. The src/index.js file has been updated to use the api_dev_key from the new secret.json file. The package_installer.bat file has been updated to create the secret.json file in the /src directory for storing hidden credentials. The CONTRIBUTE.md file has been updated with instructions for modifying these credentials.
