Does this pull request change what data or activity we track or use?

No, it does not.

Testing instructions:

• On the web: Navigate to the editor for a post with an existing VideoPress block or go through the steps to add a new one.
• In the Post and preview section of the block's settings, toggle the Video preview on hover option on.
• Verify that the autoplay setting is no longer usable under the Playback section and save the post.
• In the app: Navigate to the editor for the post you just saved.
• Tap on the VideoPress block to then open its settings.
• Select Playback Settings and verify that the autoplay setting is no longer usable. It should display the same note as the web.

LGTM 🎊 ! I tested using WordPress/gutenberg#50560 in Gutenberg and confirmed these changes work as expected.

Good idea bout adding RNMobile in the logs, I noticed when checking the VideoPress CHANGELOG that it's not clear which ones only impact the native version. Maybe we can take this as a standard for future PRs, WDYT?
