[svt] Extract timestamp and thumbnail in more cases (#27130)

Add timestamp, set to "valid from" which i think could been seen as publish time.
Add thumbnail in more cases, seems to was only done in the embedded data case for some reason.
Switch svtplay test url to an existing video and also one with no expire date.
Also add an additional thumbnail url test regex.
