fix: Pass disabled prop to hidden input in NumberField

[tklepzig]

When passing isDisabled to the NumberField, it was not passed to the underlying hidden input, which is rendered when a name prop is given.
This currently results in the value of the NumberField being included in the form values when submitting a form, even if it is disabled.
