Support DateTimeRangeValidator

[bwaidelich]

Description

https://neos.readthedocs.io/en/stable/References/PropertyEditorReference.html#property-validation
lists all supported property validators, including DateTimeRangeValidator. But that is in fact not available.

Steps to Reproduce

1. add a property of type DateTime to a Node Type definition (see below)
2. use the DateTimeRangeValidator to only allow dates in the future
3. Create an instance of the node in the Neos backend and specify a date in the past

Example:

'Some.Package:Some.Node':
  # ...
  properties:
    'date':
      type: DateTime
      validation:
        'Neos.Neos/Validation/DateTimeRangeValidator':
          earliestDate: 'now'

Expected behavior

The validator prevents the node from being created

Actual behavior

The validator is silently ignored

Any plans or workaround to support DateTimeRangeValidator in Neos 7.3 @bwaidelich?
The validator is available in the Documentation 😆

Any plans or workaround to support DateTimeRangeValidator in Neos 7.3

I don't have any, but I would hope that we'll be able to support all core (and custom!) validators at some point (without having to re-implement them all in JS)
