feat: Expand environment variables in file paths for DirectoryFileCounter and TextFileLineCounter

This update enhances the `DirectoryFileCounter` and `TextFileLineCounter` classes by expanding environment variables in file paths using `os.path.expandvars()`. This change allows these classes to correctly handle paths that include environment variables, improving their flexibility and usability in various environments.

- **DirectoryFileCounter**: The `execute_file_counter` method now expands environment variables in the `directory_path` before performing directory operations.
- **TextFileLineCounter**: The `execute_line_counter` method now expands environment variables in the `file_path` before reading the file.

This fix ensures that paths containing variables such as `%userprofile%` are properly resolved, enabling more dynamic and environment-aware file handling.
