parse of date with duration cause error

Issue

Parsing duration with dates does this:

>>> pendulum.parse("2025-03-10/P3D")
...
TypeError: Date.add() got an unexpected keyword argument 'hours'

However, adding an hour to the date string works:

>>> pendulum.parse("2025-03-10T00/P3D")
<Interval [2025-03-10 00:00:00+00:00 -> 2025-03-13 00:00:00+00:00]>

It seems the internal datetime object is type Date, which doesn't support add(hours=...)
