[packman] libheif update built but publishing failed, breaks blender

[pallas wept]

Hi packman team,

libheif was recently updated to 1.20 and pmbs says it is published, but it is not on the repo (checked several mirrors), which still has the old 1.19 package. Looks like the build service might have glitched?

This causes the recent update to blender to fail to start, so probably will effect more users. I thought I should let someone know, hope this is helpful.

PS A long time ago, I applied for a pmbs account, but it said I had to mail this list. Since I am doing that now, I wonder if someone might approve my application? :) Thanks!
