Show Form TypeScript support in documentation

[Tobbe]

@Philzen mentioned in a comment on another issue that it would be good to show how one can use types with our forms, and I agree!

So I'm writing up this issue so we don't forget 🙂

He mentioned adding it to the tutorial, and that's a good call. I'm not sure if anyone has gone through the tutorial and updated it since the TS Strict mode PR #5491 got merged. So it's possible the tutorial is lacking in more places.

We also have a page on forms in our reference section https://redwoodjs.com/docs/forms that could show how to use types

This example at the top could have a JS/TS toggle

In fact, all code examples should probably have a JS/TS toggle

The <Form> Explained section should explain the <Form<FormData>> syntax

And in https://redwoodjs.com/docs/forms#using-formmethods we should show const formMethods = useForm<FormData>()

How do we reproduce the bug?

May be out of scope, but while we're at it, i'd really love to see the 2nd parameter passed of onSubmit also documented somewhere. From the current tutorial and docs it is missing that that includes the submit event, which is the default first parameter for non-Redwood submit callbacks.
