Fix VideoAnalyzerTest#test_analyzing_a_rotated_HDR_video failure with ffmpeg < 5.0

The VideoAnalyzer uses ffprobe (part of ffmpeg) to determine the
rotation of a video. The VideoAnalyzer#angle returns tags["rotate"] if
it is available, else it attempts to get "rotation" from the Display
Matrix side_data.

However, ffprobe exhibits different behavior with different versions:
ffprobe version 4.4.2-0ubuntu on Ubuntu 22.04 returns a "rotate" : "90"
tag.

In contrast, ffprobe version 6.0-6ubuntu1 on Ubuntu 23.10 does not
return the "rotate" tag; instead, it determines the angle from the
display matrix side_data, which returns "rotation": -90.

To account for this difference, we now check for both values in the test.
