Is this necessary. Will the call to super.validate above not do the same?

No, it will only validate with the validator on the source, so it will not enforce the validator on the delegate parameter without this.

The additional cases I added in the tests show this.

I see what is going on. the call to validator in the base class will use all validators stored as part of _vals. Since this pr prevents you from adding any validator to that list it will always be empty so that line does nothing on this pr. However prior to this pr adding a validator to the DelegateParameter would cause it to be added to the parameters _vals list and used. This makes me suspect that the tests as is would also pass on main. #6832 seems to confirm this too so I am not completely sure if this pr is required

ParameterBase supports multiple validators via the add_validator etc logic. We need to consider if we want to support that here too.
Add
valsproperty and@vals.setterto qcodes.parameters.delegate_parameter.DelegateParameter to propagate the Validator from source to DelegateParameter.
