BE: Chore: remove unnecessary architecture check in unit test

[yeikel]

What changes did you make? (Give an overview)

The existing logic was unnecessary because the confluentinc/cp-kafka image is a multi-platform image and the docker engine will pick the appropriate version as needed

How Has This Been Tested? (put an "x" (case-sensitive!) next to an item)

• Unit checks
• Integration checks
• Covered by existing automation

Checklist (put an "x" (case-sensitive!) next to all the items, otherwise the build will fail)

• I have performed a self-review of my own code
• I have commented my code, particularly in hard-to-understand areas
• I have made corresponding changes to the documentation (e.g. ENVIRONMENT VARIABLES)
• My changes generate no new warnings (e.g. Sonar is happy)
• I have added tests that prove my fix is effective or that my feature works
• New and existing unit tests pass locally with my changes
• Any dependent changes have been merged

This didn't work previously for some reason, have you tried running it on arm?

[Haarolean]

This doesn't work, running tests brings up non-arm 7.2.1:

$  docker ps -a | grep cp-kafka:

@Haarolean I am surprised that this happened because I had success in another M1 Mac with this. When I tested this I used the multi-platform hash instead of a tag and I am not sure if that matters

Could you please share the output of

docker pull docker.io/confluentinc/cp-kafka:7.8.0
docker inspect docker.io/confluentinc/cp-kafka:7.8.0 | grep "Architecture"

After that, I am curious what you see if you run using the Multi-platform digest instead:

docker pull docker.io/confluentinc/cp-kafka@sha256:adc392d28a1e99e8c9a1ec7f087e9e91041837b35b8b7cc8b8a691b82dd581b0
docker inspect docker.io/confluentinc/cp-kafka@sha256:adc392d28a1e99e8c9a1ec7f087e9e91041837b35b8b7cc8b8a691b82dd581b0 | grep "Architecture"

Also, could please confirm what version of docker are you using?
