Shaves-off about 3 minutes from usage of ARM instances on CI (#24052)

Preparing airflow packages and provider packages does not
need to be done on ARM and actually the ARM instance is idle
while they are prepared during cache building.

This change moves preparation of the packages to before
the ARM instance is started which saves about 3 minutes of ARM
instance time.
