fix(core): replace references to obsolete addListener/removeListener

As per https://developer.mozilla.org/en-US/docs/Web/API/MediaQueryList

Not a big deal... just produces some linting warnings for me in my resulting package 🙂

Updated.. I didn't read the MDN article closely enough 😓

addListener() Deprecated
Adds to the MediaQueryList a callback which is invoked whenever the media query status—whether or not the document matches the media queries in the list—changes. This method exists primarily for backward compatibility; if possible, you should instead use addEventListener() to watch for the change event.
