chore(ci): temporarily disable ARMHF runners (#2083)

The docker images we used were discontinued upstream, we either need to:

* drop 32-bit ARM validation, keep publishing builds since they
  are cross-compiled from AMD64 Linux anyway

* drop 32-bit ARM validation and releases altogether, looking at stats
  there are only tiny amounts of 7-day active users who pull from the
  APT repository

* find a replacement for this runner
