/**
 * Util to merge two objects deeply. Will merge the source object into the target object.
 *
 * Note: This does not merge two arrays, it only replaces them (i.e. [1, 2] and [3, 4] would become [3, 4]).
 * Objects will be deeply merged instead of immediately replaced.
 *
 * NOTE: This will be replacing `mergeDeep` that exists in hub-components utils.
 *
 * adapted from https://gist.github.com/ahtcx/0cd94e62691f539160b32ecda18af3d6?permalink_comment_id=3120712#gistcomment-3120712
 * @param target - the object to merge into
 * @param source - the object to merge from
 * @returns the merged object
