Update ember-composable-helpers (#1980)

## Purpose

There are two major parts to fixing the try-invoke deprecation. The first is updating ember-composable-helpers, and the second is removing ember parachute. This handles the first. The second will be part of Search Phase 2 once the branded registries discovery page, which is the page that uses ember-parachute, is removed.

## Summary of Changes

1. Update ember-composable-helpers
