fix: Resize plugin, add destroy check

[nicolechung]

Similar to: https://github.com/CrowdStrike/ember-headless-table/blob/02b84b0069e621bfcf1b9439206c7043c9dd7dc0/ember-headless-table/src/plugins/column-resizing/resize-observer.ts#L38

The ResizeObserver checks to see if the table is destroyed, if it is, it does not create a new ResizeObserver.

This is missing in the plugin, which causes this error: Uncaught Error: You attempted to get the value of a helper after the helper was destroyed, which is not allowed
