Next Server Actions example doesn't account for pending status of server action

[icopp]

Describe the bug

When submitting a form, only the client-side state is taken into account for isSubmitting, canSubmit, etc. The server pending state isn't considered at all.

Your minimal, reproducible example

Steps to reproduce

In the given example, submit the form and see that the "Pending" label changes, even while the "Submit" label and button status don't.

Expected behavior

The form should be treated as submitting whenever the server action isPending flag is true.
