Refactor package-dependencies tool for global usage

- Updated package-dependencies.ts to include a shebang for execution as a script.
- Changed the main entry point in package.json to point to the compiled JavaScript file.
- Added bin configuration in package.json for global command usage as 'java-dependency-mapper'.
- Enhanced README.md with instructions for global installation and usage of the tool.
