Add Default Options for Color Picker Custom Element Class

[skovy]

We are experiencing an error when the custom element for the Color Picker is being cloned. It's a bit of a long story, but we are using Turbo Drive which calls cloneNode and we cannot easily prevent it. Since this is a custom element, I think it's a reasonable expectation it should support the HTMLElement helpers.

This error can be reproduced in a browser by selecting the xy-color-picker custom element in the respective "Elements" tab. Then going to the JavaScript "Console" and typing $0.cloneNode() where $0 is a reference to that element (Chrome devtools).

This errors because cloneNode is constructing the element without any arguments, which this constructor assumes.

This PR addresses this error by defaulting options to {} which avoids options being undefined.
