chore(migrations): Bump atlas migration container image

[javirln]

This patch upgrades Atlas to v0.32.1-819f32c-canary to address the CVE GHSA-vvgc-356p-c3xw

It also reverts the Atlas version in the common script to the previously working one, as the updated version caused issues in that context.

New version of Atlas does not show any CVE at this moment:
