Bug report

When using the readonly method for the Kendo UI DatePicker when toggling to remove the readonly attribute, the aria-readonly attribute remains.

Reproduction of the problem

1. Go to this dojo.
2. Inspect the DatePicker element.
3. Toggle readonly on and off for the DatePicker.

Current behavior

The aria-readonly attribute is still included in the Kendo UI DatePicker.

Expected/desired behavior

The DatePicker's readonly method should work like the DateTimePicker's method.

Environment

• Kendo UI version: 2021.2.511
