Intent to bump SVT-AV1

Hello, This week, I will rebuild svt-av1 and its dependencies in a side tag. Tests were done this weekend on COPR and compatibility with FFmpeg 6.1.1 was determined to be functional. I will need the help from RPM fusion people. Libheif and Libheif-freeworld will be updated during the process (minor release but allow to build with svt-av1). It will also backport a fix for a small CVE. Best regards, Robert-André
