feat: Remove 'pageHide' from page end-of-lifecycle listener

[ptang-nr]

Remove pageHide from page end-of-lifecycle listener since browser agent support for Safari 14.4 is deprecated

Overview

Previously in support of Safari 14.4, we had retained the subscription to pageHide event for detecting when a page is entering a hidden state. Safari 14.4 has now aged out of our current supported versions, so we are removing the pageHide logic. Page unloads should now be detected via visibilitychange events across all supported browsers.
