Add documentation on how to create a Wagtail form page

[Amalearner]

Creating a form page in Wagtail is a useful feature that allows users to set up single-page forms. Currently, there is no documentation available on how to create a form page in Wagtail.

Why it should be documented:

To help users understand how to create a form page
To provide clear instructions on how to add form fields to the form page

How it should be documented:

Provide a step-by-step guide on how to create a form page in Wagtail
Include examples and screenshots to help users understand the process
Explain how to add form fields to the form page and customize the form builder

Thank you @Amalearner, this seems like a sensible suggestion to me. I don’t think this should be too reliant on screenshots however (one would be plenty).

Awesome! @thibaudcolas already trying to work on the content format. If that's fine by you. Then I can create a pr with a link to the Google docs in what I've come up with. What do you think?

As I mentioned, I plan to keep contributing.

Also, please try to make the language as general as possible, due to the fact that every site's form page(s) will be different, depending on how it was implemented by the developer(s) of that site.
