Try running "npm install" in your functions directory before deploying

[AmilKey]

When attempting to deploy Firebase, the following error occurs:

Try running "npm install" in your functions directory before deploying.

This happens because the necessary npm packages are not installed in the functions directory. To avoid this error and automate the process, we should update the deployment script to automatically install packages before deployment.

Proposed Solution: Add a step to install npm packages in the deployment script
