chore(templates): fix: the contact page of the website template throws an error in live preview (#10785)

Fixes: #10787

The underlying problem is that there are types in the form builder
plugin that are unnecessarily `any` or `unknown`.
Here in the website template this was being circumvented with a function
that was not really needed (buildInitialFormState), and with new unknown
types (Value, Property and Data).

Since create-payload-app fetches from the latest commit instead of the
latest release, it is necessary to first merge
#10789, and once the next
release is done this PR can be merged.
