ArgumentError feedback should report the original offending value

[ddnexus]

The ArgumentError feedback should report the value of the original offending variable passed to the constructor.

Currently it reports the (possibly transformed by to_i) value of the instance variable. If you pass page: 'foo' then you should get an argument error saying expected :page in 1..23; got "foo" instead of expected :page in 1..23; got 0.

Would it be possible to change the behaviour so it redirects to page=1? Users have to manually enter a wrong page value to get there, but I feel like a 500 is a bit harsh.

With old versions you can rescue ArgumentError and check the message for the variable and the value.
With the new version you have Pagy::VariableError with the accessors for the offending variable and its value.
