The PROD cachie build often fails (especially in v2-8-test) when it tries to rebuild the PROD cache in parallel on ARM. There is some weird inter-buildx problem with it and some people experience it sometimes as documented in moby/buildkit#2367
Instead of finding the root cause, we change this specific job in CI to run sequentially. This changes the time it will take to update cache - but not as much as 4x because the builds do not parallelise very well anyway. Likely instead of 8m we will get maybe total 15m, and since this is just cache update after everything else has completed, it does not matter too much if it runs a little longer.
