Follow up for video meta

Created by: bretthayes

This is a follow up PR for #5440 which replaces the YouTube thumbnail URL with the latest URL.

The previous URL was causing the inline social player not to render and caused inconsistent results.

Test

1. Ensure prettier has standardized the proposed changes.
2. Test and share any podcast post that has a YouTube video ID on social media using the staging preview link. Most notably, test the /podcast/max-howell and /podcast/ravi-parikh posts. Optionally use the FB and Twitter validator.
