Feature: improve VideoCard Performance (+ remove GifVideo)

• Now if the video URL is a video.igem.org domain it will fetch the thumbnail and display it instead of loading the iframe
• You can now add a customThumbnail as parameter (which make the GifVideo deprecated → I removed it)
• The usage of VideoCard is unchanged

Note: One of the original idea was to replace the props to enforce to use video ID instead of embed URLs. The problem I run into is that :

1. There are also URL that are not on the video.igem.org domain, so it will require maybe another prop field for this ? (but this is minor we can work around this)
2. There are two types of video.igem.org links, videos (ex: https://video.igem.org/videos/embed/1cfcd8d9-9a4e-42ae-9451-21267b4860b4) or video-playlists (https://video.igem.org/video-playlists/embed/1cfcd8d9-9a4e-42ae-9451-21267b4860b4) and if we only ask for the ID on the props, we can't get the thumbnail because of the peertube api route for the thumb that are different.
