Subject: [PATCH] Switch to using emulation for image building (#41959)
 (#41962)

Until we can use ARM hardware to build images with the new ARC
architecture https://github.com/apache/airflow/issues/41935
we switch image building to emulated builds. They are 10x slower
but it's better than nothing.

(cherry picked from commit 8267c332b8d3756e1293e477517102abb292679e)
