feat(cli): use correct architecture in worker images

[bernardobridge]

Description

We now build x86_64 and arm64 images. Fargate will use x86_64 image by default (as it currently does), and Fargate will use arm64 by default (as it currently does).

Notes:

• We don't test against arm64 in PRs due to how long it takes to build. We will make some changes separately to run that in main against a canary
• Lambda functions will contain the architecture in the name to piggyback on existing name mechanism to determine if a new function is needed

Pre-merge checklist

• Does this require an update to the docs? I don't think so, since no default behaviour was changed
• Does this require a changelog entry? It could be highlighted, yes

Note: disregard failing test, it's a bug in zipfile introduced in https://github.com/artilleryio/artillery/pull/2767/files#diff-031b22251942a138a35ea32b4c6f9f4188824a499012ab4ca3a36be352d77568L202 .

Very easy fix (just use noPrefix if noPrefixPosix isn't there), but no point in fixing since zipfile is being deprecated in the other open PR, so all that code will be deleted shortly.
