I think after this change what we claim on https://github.com/open-telemetry/opentelemetry-collector/blob/main/docs/platform-support.md#tier-2--secondary-support is no longer correct. But realistically, the current arm runners do not provide good test coverage, they are too flaky, so maybe we can just downgrade our support for Linux ARM for now

Pinging @atoulme for review on this as well since he's the owner of linux/arm

@mx-psi as per your suggestion, i've updated the supported platforms doc to reflect this change

[atoulme]

I am acknowledging this change. I didn't get a chance to review and weigh in. I will take further actions to bring back support of linux/arm64 back to tier 2. Thanks.
