ci: labels test does not work with GH arm runners

[kkourt]

The e2e labels test fails on the GH arm runner ("ubuntu-22.04-arm64"):

labels otel-demo-opensearch-0 0/1 Pending 0 15m

As a result, the test fails:

d: PodChecker: PodLabels[app.kubernetes.io/component] (app.kubernetes.io/component=loadgenerator) check failed: 'loadgenerator' does not match full 'otel-demo-opensearch'"
