Flaky TestMetrics

[lburgazzoli]

What happened?

The test is marked a problematic and fails for a slightly different metric values:

https://github.com/apache/camel-k/blob/4114271b6ccbc74e52a87455123fb522bbbf84a1/e2e/advanced/operator_metrics_test.go#L48-L55

We should investigate the reason of the flakiness

Probably not an issue (at least, not in upstream CI). See #5484

[lburgazzoli]

That is an error I observed upstream at least on two unrelated PRs

Let's add it to the flakiness bucket then.
