getRemoteThumbnailUrl() for YouTube returns cached thumbnail

Problem/Motivation

getRemoteThumbnailUrl() is returning video thumbnail cached by youtube CDN.

web/modules/contrib/video_embed_field/src/Plugin/video_embed_field/Provider/YouTube.php getRemoteThumbnailUrl() method.

Steps to reproduce

1. Create a media with youtube embedded video and check the thumbnail.
2. Change the thumbnail from youtube.(from Youtube studio)
3. Delete previously created media.
4. Now create media again with same youtube video link and check thumbnail.

You can see the old thumbnail in this newly created media.

Proposed resolution

This is because Youtube CDN caches the thumbnail images and requested thumbnail images will be served by CDN.
We can add current timestamp as query parameter to the request uri.
