Jetpack Focus: Intercept reader links in p4 and redirect to main view

[zwarm]

This PR reverts the revert in #17851 to address the case where reader web links are not being redirected to the main view. Yes, this means that for these particular web links an overlay won't be shown, but for now that is okay (as the overlay was a last minute addition as a nice-to-have). We will eventually sort out the showing of the overlay for these instances, but the immediate need is to stop the user from being dropped into an feature of the app which has been removed.

To test:
To test:
Decompress and download the attached links_helper.html file to your device (github doesn't support html file attachments)
