- Added a new `_generate_format_help_and_examples` function to dynamically generate help text and examples for export formats.
- Enhanced the `configure_parser` function to include a `--format` argument, allowing users to specify the export format.
- Implemented environment exporters for JSON and YAML formats, enabling serialization of conda environments to these formats.
- Updated the `execute` function to handle different export formats based on user input or file extension.
- Modified tests to validate the new JSON export functionality and ensure backward compatibility with YAML exports.

- Corrected the attribute access method for `base_url` and `subdir` in the export_explicit function to use `getattr` instead of `getatter`.
- This change improves the reliability of the environment export functionality by ensuring proper attribute retrieval from package objects.

…uration

- Added logic to override the environment's channel config when --override-channels is used with explicit channels, ensuring only requested channels appear in the exported environment file.
- Removed unused `override_channels` parameter from the Environment class constructor for clarity and maintainability.

- Included the channels argument in the execute function to enhance the environment export process.
- This change ensures that the specified channels are considered during the export, improving the accuracy of the exported environment file.

- Replaced instances of the flask package with colorama in test_create.py, test_main_export.py, and test_prefix_data.py to ensure consistency in testing.
- Adjusted assertions and comments accordingly to reflect the change in the test package.
