feat: Add refresh and setData capabilities to useRequest
This commit introduces two new functionalities to the `useRequest` hook: 1. **Refresh Last Request:** A `refresh` function is now returned by `useRequest`. This function allows re-executing the last request with the exact same parameters that were used. If no request has been made yet, `refresh` will do nothing. 2. **Set Request Data Imperatively:** A `setRequestData` function is now returned by `useRequest`. This allows setting the request payload programmatically before calling `run`. The `run` function will prioritize this data if set. The data set via `setRequestData` is cleared after the request executes, ensuring it's a one-time override unless called again. These changes enhance the flexibility of the `useRequest` hook, allowing for easier re-fetching and dynamic modification of request payloads. Unit tests have been added to cover these new functionalities, ensuring they work as expected and to prevent regressions.
