[Suggestion]: improve <Form> documentation to explain how to keep form state after submission

Summary

https://github.com/facebook/react/issues/29034 raises concerns about actions resetting forms. There are many use cases where developers would want to prevent the form from resetting. Since React's behavior is not expected to change, the docs should explain to users how to control form resets and preserve the form's previous state.

Details

I do not know the best way to provide this information. Some suggestions include:

1. Add a deep dive on when to use onSubmit vs action props.
2. Include an example of opting out of automatic resets using an example based on @eps1lon comment here: https://github.com/facebook/react/issues/29034#issuecomment-2143595195. The issue has several other workarounds that may or may not be endorsed by the Rect team.
3. Update the Handling multiple submission types example so that the "Save draft" button will keep the text of the form.

Start with the React

reference page, especially the “Handling multiple submission types” example, and review issue #29034 and the linked comment for the reset behavior and proposed workarounds. Done means the page clearly explains how to preserve form state after submission and includes an agreed, accurate example without endorsing unsupported behavior.
