-- `*_label` (`xs_label`, `s_label`…): Adjust size label names
-- `*_max_size` (`xs_max_size`, `s_max_size`…): Adjust which amount of changes you consider appropriate for each size based on your project context
-- `fail_if_xl`: Set to `'true'` will report GitHub Workflow failure if the PR size is xl allowing to forbid PR merge
-- `message_if_xl`: Let the user(s) know that the PR exceeds the recommended size and what the consequences are
-- `github_api_url`: Override this parameter in order to use with your own GitHub Enterprise Server. Example: `'https://github.example.com/api/v3'`
-- `files_to_ignore`: Whitespace or newline separated list of files to ignore when calculating the PR size, regex match is supported.
