getFlowTransformRules
A helper function that generates module.rules configuration for handling Flow type annotations in JavaScript files. The rules use @callstack/repack/flow-loader to remove Flow types from the code before other processing.
This helper function is a part of getJsTransformRules.
This helper function is only relevant when using Rspack as your bundler. If you are using webpack with babel, you don't need to use this helper function, since it's already included as part of @react-native/babel-preset.
