Use HTML `datetime-local` input with DateTimeField

[JacobsThierry]

When using DateTimeField and rendering a template, the html tag generated look like this :

The type is "datetime" which does not mean anything in vanilla HTML. So the browser display the field as a text Field.
The type should be "datetime-local"

Tested with WTforms 3.0.1

In the widgets is define DateTimeLocalField

class DateTimeLocalField(DateTimeField):
    """
    Same as :class:`~wtforms.fields.DateTimeField`, but represents an
    ``<input type="datetime-local">``.
    """

    widget = widgets.DateTimeLocalInput()

    def __init__(self, *args, **kwargs):
        kwargs.setdefault("format", ["%Y-%m-%d %H:%M:%S", "%Y-%m-%dT%H:%M:%S"])
        super().__init__(*args, **kwargs)

Indeed it seems that <input type="datetime"> is now obsolete. I don't know if we should remove the field in wtforms, or if we should keep it for some compatibility reasons.
