Remove package-lock.json files and add to .gitignore

[AndrewBarber]

This PR removes package-lock.json files from git tracking and adds them to .gitignore to prevent them from being tracked in the future.\n\nThis follows best practices for npm packages, as package-lock.json should not be committed to repositories for libraries that will be consumed by other projects. For npm packages like this one:\n\n- It allows consumers to resolve dependencies based on their own environment\n- It prevents potential conflicts with consumers' dependency trees\n- It provides more flexibility with dependency version resolution\n- It aligns with npm's official recommendations for published packages\n\nThe changes include:\n1. Adding package-lock.json to .gitignore\n2. Removing existing package-lock.json files from git tracking
