Extended original InertiaJS props and method types into PrecognitionFormProps

[juanparati]

I was able to extend original InertiaJS props and methods types into the PrecognitionFormProps, so Typescript linters can provide scope over the original InertiaFormProps.

This method is better that proposed in #71 because it's not required to wrap methods for InertiaJS.

Advantages:

• It will automatically inherit automatically all methods and props from different InertiaJS versions.
• Easy to maintain, it only requires to write definitions for the resulted object of Precognition "useForm".

Appreciate your work here.

Heym, @juanparati, thank you so much for pushing this along. I'm circling back to this now.

I'm going to close this PR in favour of https://github.com/laravel/precognition/pull/88/files, simply because it is more recent and doesn't have any conflicts.

Thank you again.

@timacdonald : Thanks for take a look to my PR. I will look forward to precognition with Inertia 2 in the future.
