Enhance test environment configuration and CLI tests for consistent color output

Update the GitHub Actions workflow to set environment variables for color output during test execution. Modify CLI test cases to ensure consistent terminal color settings by passing the FORCE_COLOR and TERM variables to the CliRunner. Adjust snapshot files to reflect the updated color formatting in CLI help and error messages.
