This reverts commit c19a51e.

@cnkk we have two alpine image references in our Dockerfile and only one got updated. This may lead to unpredictable build oddities.

actually even with the revert they're diverged already

[cnkk]

Good point. I missed this earlier

[ruslandoga]

Small nitpick, it doesn't seem to matter that the patch versions are different since the final image runs apk upgrade

For reproducible builds it might make sense to remove apk upgrade since it makes alpine:3.18.0 practically become alpine:3.18.2

Ah great, thank you for looking into it.

This PR was a knee-jerk reaction to some random errors (of unknown then source) and I only remembered we've had issues with Erlang's SSL in the past due to a imprecise bump.
