Images in video posters

Hi,

Could you add support for images in video posters to Jetpack?

For example, there is the following code:

<!-- wp:video {"id":43452,"poster":"https://domain.com/wp-content/uploads/2022/11/video-poster-image.jpg"} -->
<figure class="wp-block-video"><video controls poster="https://domain.com/wp-content/uploads/2022/11/video-poster-image.jpg" src="https://domain.com/wp-content/uploads/2022/11/video.mp4"></video></figure>
<!-- /wp:video -->

If Jetpack would automatically add i0.wp.com to the image files (e.g. video-poster-image.jpg) that relate to the video posters, that would be great. Since it would solve the problem of the drop in PageSpeed scores. Right now this has to be done manually.
