Improve "Date" field validation

## Description

More options to restrict the date element e.g. no dates in the future and no earlier than two years from the date of filling out the form

-- Only future dates
-- Only past dates

**Observation from client in the API file attachment Beta cohort:**

Your form date field does not limit month and year to only 2 digits.

It validates correctly, but it does not prevent long numbers. …

It also does not allow for leading zeros, which is fine, but feels a bit unnatural for dates.

> Si nous avons des questions avec des dates, mais nous voulons que celle-ci ne soit pas dans le passé, est-ce que nous avons l’option qu’il y ait une erreur qui s’affiche lorsque le client veut continuer le questionnaire pour qu’il puisse changer la date?
