Resolve "Validate the PreviewNavigationBar parameters values against their type."

What is in this MR

This MR adds validation to PreviewNavigationBar so that we validate the value against the parameter's type when a parameter's value is changed. If they clash (for now, just if you enter a non-integer value in an integer parameter) then a red border appears around the input.

How to test this MR

• Create a few page parameters of both types.
• In the editor, experiment with changing values. If you have an integer parameter and enter text, it will display a red border.
• Only valid parameter values will persist.
