Remove "viewing" from the YouTube video link that displays when embedded videos don't render

Why is this change being made?

The message that displays when an embedded YouTube video cannot be played is a bit confusing because "viewing" is part of the link, which makes it seem like it would link to instructions on how to view the video, not the video itself. This feedback came up as part of the Release Post review process that is done in the view app.

This MR will change the link to be just "this video" so it's clear the link goes to the video.
