Add .gitignore file creation in init command

- Implemented a function to create a .gitignore file during the initialization of Codacy configuration.
- Updated .gitignore to include cli-v2 and removed unnecessary entries.
- Ensured the .gitignore file contains relevant entries for Codacy CLI tools.
