refactor: remove --remove-me option

The --remove-me option is removed as it's considered unnecessary.
Users who want to remove the package can simply run:
composer remove dev-to-geek/laravel-init

This simplifies the codebase and reduces complexity.

Changes:
- Removed --remove-me option from command signature
- Removed conditional block that handled package self-removal
- Removed related tests (2 tests)
- All remaining tests passing (27 passed, 62 assertions)

This is a cleaner approach that follows the principle of doing one thing well.
